AUTO HOLD Function
The 732 series of multimeters can automatically retain the measured
value when the testing leads are handled as described below.
a) Press the AUTO.H key. (The display shows the 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 symbol.

g) To cancel this function, press the AUTO.H key once again.
(The symbol disappears.)

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 function 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 pcs.).
• 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.
Diode Test
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 input terminal.
c) Connect the testing leads to the diode and then
read the multimeter when it stabilizes.
Capacitor Check
*This function is not supported on the 73201/04 multimeters.
d) When the test is complete, set the function
switch back to the OFF position and turn off
the multimeter.
(1) Forward-bias Diode Test
(2) Reverse-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.
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.
• 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.
Current Measurement (μA/mA/A)
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 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.
Zero calibration is only effective when the 20 nF range is selected.
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 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.
CAL
• 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.
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-measurement range, a protection fuse may blow. If this happens,
replace that fuse. The multimeter contains the following two types of fuses:
• 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.
• Type F05: 500 mA/250 V fuse
• Type F02: 15 A/250 V fuse
