Ohaus SD Series Bench Scale INSTRUCTION MANUAL • The contents of this manual applies to all models of the SD Series Bench Scale. • Calibration weights are not provided with this product. • For best results, use the product within the specified operating temperature range. • For best accuracy, perform your measurements in a clean environment, free of electrostatic and magnetic fields, dust and dirt, moisture, vibration and air currents. • Use your SD Series Bench Scale with care, gently loading items to be weighed on the center of the platform. Avoiding rough treatment will aid in extending the life of your Scale.

Introduction This manual covers operation for the Ohaus SD Series Bench Scales. Unpacking SD Series Bench Scale is shipped with the following components: • Indicator • AC Power Adapter • Scale Base • This Instruction Manual • Mounting Brackets • Warranty Card Leveling Scale Platform The Scale Base should be placed on a level, stable surface before operation. Models SD75L and SD200L are equipped with adjustable leveling feet. Adjust the four leveling feet under the platform to level it. Power Options AC Adapter Operation • The AC Adapter (included) may be used to power the system when battery power is not available. • Check that the AC input power as marked on the Adapter matches the available power source. • Connect the round plug of the AC Adapter to the power input jack at the side of the Indicator housing. See Figure 1. • Plug the AC Adapter into an AC power outlet. Figure 1. Connecting Adapter Plug to Indicator.

Battery Installation (Optional) • Open the battery cover on the bottom of the Indicator and install three “C” size (LR14) alkaline batteries into the compartment. Orient the batteries as shown on the inside cover. Close the battery cover. NOTE: Batteries are not included. Figure 2. Battery Installation. CAUTION: Do not dispose of used batteries in domestic waste. Follow the proper disposal or recycling requirements in accordance with local laws and regulations. Indicator Mounting and Placement Options • Table Top Placement: The Indicator may be placed on a flat table surface without additional hardware. Four rubber feet provide reduced slippage on most surfaces. • Direct Wall Mounting: The Indicator may be mounted directly to a wall using two screws (not included). Select appropriate size screws that fit into the holes at the bottom of the Indicator housing. See Figure 3. When mounting to a wall without a solid backing, use appropriate anchoring hardware.

Figure 3. Direct Wall Mount Arrangement. • Bracket Wall Mounting/Table Mounting: Attach the two mounting brackets as shown in Figure 4. Position the Indicator where desired on the wall or table. Install 2 screws (not supplied) into the ends of each bracket to secure them to the surface. When mounting to a wall without solid backing, use appropriate anchoring hardware. MOUNTING NOTES: 1. When attaching brackets: Insert round pins into holes at bottom of Indicator, slide each bracket back to lock in place. 2. Mounting brackets may be attached in two different orientations to provide optimum viewing angle. 3. Some mounting positions may require that the brackets be attached to the work surface before being attached to the indicator. Figure 4.

Product Features & Operation Figure 5. Indicator Panel Controls. Two Button Keypad • ON/ZERO Off : A short press turns on the scale when it is off. When the scale is on, a short press zeroes the scale, and a long press turns the scale off. • UNITS Cal : A short press changes the weighing unit and weighing mode. A short press initiates countdown during Dynamic Weighing Mode. A long press initiates the calibration process. Display Window • Large 7-Segment Numeric Characters: Weight (mass) values are shown using 4 digits including negative sign and decimal places. Prompts for calibration and possible error conditions are also shown using these digits. • Stable Reading Indication: A * will appear in the lower left corner of the display to indicate when the reading is stable. • Weighing Unit Indication: The weighing unit selected appears on the right side of the display. • Dynamic Weighing Mode Indication: A • will flash next to the selected unit during this mode. SD

• Low Battery Indication: The battery symbol on the left side of the display indicates a low battery condition. When first displayed , approximately 12 hours of operation remain. When the battery is fully depleted, the scale will momentarily display “Lo bAt” and shut off. Operation • Power Up Test: When the ON/ZERO Off button is pressed, the scale is turned on, all display segments will appear for a short time, followed by the software version. The display will then reset to zero. • Zero Function: By pressing the ON/ZERO Off button, the scale display returns to zero. When adding additional mass, the ON/ZERO Off button may be used repeatedly until the full capacity of the scale is reached. When a container is used, the ON/ZERO Off button may be used to simulate a Tare function. Additional mass may then be added as a NET weight. When removing both the sample and container from the scale, a negative value may be displayed. Zero the scale again before subsequent usage. NOTE: The ON/ZERO Off button will perform a true zero setting function when displayed values are within +2% of full capacity. Above 2%, the range is limited to full capacity by subtraction. • Negative Values: When a load is removed from the scale, any previously zeroed value will be displayed as a negative number. To return to normal operation, the negative value is cleared from the display by pressing the ON/ZERO Off button. • Overload: If the applied load exceeds the capacity of the scale, an “E” is displayed. Remove the load and the scale will return to normal operation.

• Auto Shut-Off: To extend battery life, the scale will automatically turn off after approximately four minutes of inactivity. This feature is only active during battery operation. Dynamic Weighing 1. With platform empty, press the UNITS Cal button until the indicator • flashes next to the desired measuring unit. 2. Place a mass on the platform. The scale will show “-A-”. NOTE: If using a container, press ON/ZERO Off to tare the weight and return to zero. 3. With a mass on the platform or container, a short press of UNITS Cal will start the averaging countdown from 5 seconds. 4. The averaged weight is then displayed. The indicator • stops flashing when the process is complete. 5. The display will hold until a button is pressed. 6. To repeat the process press UNITS Cal with a mass on the platform or container. 7. To Exit, remove the mass from the platform or container and press UNITS Cal.

Calibration For best results, calibrate the scale at regular intervals. (Calibration weights are not supplied with the scale.) CAUTION USE EXTREME CARE WHEN HANDLING CALIBRATION WEIGHTS AS THEY ARE VERY HEAVY. IMPROPER LIFTING METHODS OR MISUSE OF CALIBRATION WEIGHTS MAY RESULT IN PERSONAL INJURY. MULTIPLE WEIGHTS MAY BE USED TO EQUAL THE REQUIRED CALIBRATION WEIGHT. 1. Allow the scale to warm up and stabilize for a least two minutes before commencing the calibration procedure. 2. To select the weighing unit to be used for calibration, press the UNITS Cal button until the correct unit is displayed. NOTE: The calibration process can be stopped at any time by pressing the UNITS Cal button or by turning the scale off. The correct span calibration weights will need to be available before starting the calibration (see specification table). Calibration is unavailable in Dynamic Weighing Mode. 3. Press and hold the UNITS Cal button until “CAL” is displayed. 4. With the platform empty, press the ON/ZERO Off button to capture the scale zero. The display will show “-C-”

5. After the zero is captured, the required span calibration weight in the selected unit is displayed. 6. Place the calibration weight on the platform and press ON/ZERO Off button. The display will again show “-C-”. 7. After span capture, the display will return to the normal weighing mode. NOTE: The message “CAL E” will appear if an incorrect calibration weight was applied. Repeat the procedure using the correct calibration weight. Calibration Locking: By use of an internal switch, the calibration function may be locked (disabled), and unauthorized recalibration prevented. 1. With the scale powered off, remove the back housing section of the indicator by unscrewing the four screws at the bottom. 2. Slide the switch on the PCB (marked SW3) to the position marked “CAL LOCK”. 3. Reassemble the housing. 4. If required, place tamper evident sealing labels over the screw holes or over the housing edges. If later recalibration is required, the housing will need to be reopened and the lock switch returned to the original position. NOTE: When the lock switch is set to the CAL LOCK position, the power-on zero range is reduced to 10% of full capacity.
