72-14615 Operating Manual 72-14615 72-14615 Operating Manual 1 Overview Digital Bench-Type Multimeter Model 72-14615 is the maximum reading 1999 and 3 1/2 digits, models in manual range, DC / AC current type digital multimeter. This is also the extra large characters in LCD display backlight with full function, full measurement and full overload protection as well as a good product design outlook. In addition to all the conventional features include DC/AC voltage, DC/AC current, resistance, frequency, capacitance, temperature ℃, Transistor hFE, diode and continuity buzzer. This operating manual covers information on safety and cautions. Please read the relevant information carefully and observe all the Warnings and Notes strictly. Unpacking Inspection Open the package case and take out the Meter. Check the following items carefully to see any missing or damaged part. If you find any missing or damage, please contact your dealer in your country. • Operating Manual 1 piece • Test Lead 1 pair • Alligator Clip 1 pair • K Type Temperature Probe (For the temperature under 230℃testing) 1 piece • Multi-Purpose Socket 1 piece • Power Code (AC220V 50Hz DC9V/200mA) 1 piece Safety Information This Meter complies with the standards IEC61010-1 in pollution degree 2, overvoltage category (CAT II 1000V) and double insulation. If you can not follow up this operating instruction to use the meter and it reduces the chance to have an using protection. 1. Before using the Meter and Test Leads inspect both items. Do not use the Meter and Test Leads if it is damaged or the case (or part of the case) is 　removed or no reaction on LCD display. Prohibited to use the meter without housing or housing without screw fix up in order to avoid possible electric 　shock or to avoid possible damage to the meter or to the equipment under test. 2. If the damage of test leads, use only the same model number or identical electrical specifications replacement parts. 3. Do not use your finger to touch on any testing cable, connector, unused terminal input or circuit during the testing stage 4. When the meter working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken for there is danger of electric shock. 5. Selecting the correct terminal input and turn the rotary switch to select the measuring function. In case of no any idea on the value input of the 　 current, just simply test from the high value to low one. 6. Do not overload voltage or current on EITHER between terminal and terminal OR between terminal and grounding which indicate on meter limitation. 7. The rotary switch should be placed in the right position and no any changeover of range shall be made during measurement is conducted to prevent 　 damage of the Meter. 2 8. Do not use or store the meter in an environment of high temperature, humidity, flammable and electromagnetic environment. The performance of the 　meter may deteriorate after dampened. 9. The internal circuit of the meter shall not be altered at will to avoid damage of the meter and any accident 10. Replace the battery as soon as the battery indicator “ ”Appears. With a low battery, the meter might produce false readings that can lead to 　electric shock and personal injury. 11. Turn the meter off when it is not is use and take out the battery when not using for a long time. General Specifications 1.
