(1) Forward-bias Diode Test Connect the black testing lead to the cathode and the red testing lead to the anode (see Figure 1). Silicon diodes should give a reading of approximately 0.5 V and light-emitting diodes a reading between 1.5 V and 2.0 V. Note that readings close to 0 V represent a short-circuit and the "---" symbol indicates an open-circuit. (2) Reverse-bias Diode Test Connect the black testing lead to the anode and the red testing lead to the cathode (see Figure 2). Normally, the display shows the "---" symbol, indicating that the diode under test is normal. The diode is defective if the display gives a certain voltage level. d) When the test is complete, set the function switch back to the OFF position and turn off the multimeter. • Capacitor Check ( ) *This function is not supported on the 73201/04 multimeters. CAUTION To avoid damage to Instrument or equipment. Before starting measurement, be sure to discharge the capacitor under check. a) Set the function switch from the OFF position to the position. b) Plug the black testing lead into the COM input terminal and the red testing lead into the µA•mA• input terminal. c) Press the SELECT key to adjust the stray capacitance to zero (the display shows the CAL symbol). d) Connect the testing leads to the circuit under check and then read the multimeter when it stabilizes. e) When measurement is complete, set the function switch back to the OFF position and turn off the multimeter. NOTE Do not mistake the following for a malfunction! Zero calibration is only effective when the 20nF range is selected. • Current Measurement (µA/mA/A) *This fucntion is not supported on the 73204 multimeter. CAUTION To avoid damage to instrument! • Check to which mode the function dial is set before starting measurement. • A current of 11 to 20 A can also be measured if the time interval is kept within 30 seconds. The buzzer will sound if the interval exceeds 30 seconds. If this happens, immediately stop measurement. To continue measurement, wait for 2 minutes or more when restart. a) Set the function switch from the OFF position to either the µA, mA or A position. (If the magnitude of the current being measured is not known, select the A position.) b) When measuring AC current, press the SELECT key to select the AC mode. (The display shows the “ ” symbol to indicate AC-mode measurement.) c) Plug the black testing lead into the COM input terminal and the red testing lead into the A input terminal. If the current is in the order of milli-amperes or less, plug the red testing lead into the µA•mA• input terminal. d) Connect the testing leads to the circuit under test and then read the multimeter when it stabilizes. e) When measurement is complete, set the function switch back to the OFF position and turn off the multimeter.

(The display shows the A • H symbol.) b) Connect the testing leads to the object under test. c) When the reading stabilizes, the buzzer sounds. d) Remove the testing leads from the object under test. e) The multimeter now shows the measured value that it retains. f) You can repeat steps b) to e) as many times as you like as long as the display shows the A • H symbol. NOTE Do not mistake the following for a malfunction! • In DC voltage measurement, the AUTO HOLD function is only available for ranges greater than the 4 V range. • This function is not available for current-mode measurement. • In a capacitor check, the AUTO HOLD function requires a few seconds before it takes effect. • The AUTO HOLD function cannot be applied to unstable signals. g) To cancel this function, press the A • H key once again. AUTO POWER OFF Function The multimeter automatically turns off if no key is pressed for a period of 20 minutes. The multimeter will beep for approximately one minute to alert the operator before the automatic power-off function takes effect. (Pressing any key while the multimeter is beeping postpones the power-off time. Pressing any key once after the power to the multimeter is automatically turned off switches the multimeter on again.) To cancel the automatic power-off function, hold down the SELECT key and then set the func- tion switch from the OFF to the position of any desired measurement mode. (The AUTO POWER OFF indication turns off when the function is canceled.) To enable the function once again, temporarily switch the function switch back to the OFF position, and then select the desired measurement mode. Battery Replacement If the batteries fall below the normal operating voltage, the symbol turns on. If this happens, replace the batteries with new ones (AAA-size [ANSI] batteries....2). CAUTION To avoid electric shock! • Be sure to disconnect the multimeter from the circuit under test before replacing the batteries. • Replace both batteries at the same time making sure to position them with the correct polarities. To replace the batteries: a) Remove the three screws on the back of the casing. b) Open the casing. c) Take the battery holder out of the casing. d) Replace the batteries with new ones and install the battery holder back into the casing. e) Close the casing and fasten it with the three screws. Fuse Replacement If a current greater than the rated value flows when the multimeter is in the current-measure- ment range, a protection fuse may blow. If this happens, replace that fuse. The multimeter contains the following two types of fuses: • Type F05 250 V/500 mA fuse • Type F02 250 V/15 A fuse CAUTION To avoid electric shock! • Be sure to disconnect the multimeter from the circuit under test before replacing the fuse(s). • Do not operate the multimeter with the casing left open. • In order to avoid damage to the multimeter or any possible accident, use fuses of the specified rating. To replace the fuse(s): a) Remove the three screws on the back of the casing. b) Open the casing. c) Remove the blown fuse from the fuse holder. d) Install a new fuse in the holder. e) Close the casing and fasten it with the three screws.
