WARNING

■ To avoid electric shock!

• Check the testing leads before use and do not use deteriorated or damaged
ones. Check the continuity of the testing leads.

• Do not use the instrument if there is any damage to the casing or when the
casing is removed.

• Disconnect the instrument from the circuit under test before opening the casing
to replace the batteries or for any other reason.

• Avoid using the instrument if it has been exposed to rain or moisture or if your
hands are wet.

■ To avoid electrical shock or fire!

Do not use the instrument in an atmosphere where any flammable or explosive
gas is present.

WARNING

■ To avoid damage to instrument or electric shock!

The restrictions on the maximum voltage level for which the 73201, 02, 03 and
04 multimeters can be used, depend on the measurement categories specified
by the safety standards. These category specifications are formulated to protect
operators against transient impulse voltages in power lines.

2) SELECT key (73202/03) or / key (73201)*

This function is not supported on the 73204 multimeter.

This key is enabled only if the multimeter is in one of the following
measurement modes.

• Ω/ : In this mode, the key selects between the resistance

measurem ent and continuity test.

• : In this mode, the key adjusts the stray capacitance of the

testing leads and the multimeter itself to zero.
(The display shows the

CAL

symbol.)

• µA/mA/A: In this mode, the key selects between the DC and AC modes.
* The 73201 multimeter comes with the / key instead of the SELECT

key. This key is used only to select between the DC and AC modes in the
current measurement mode.

3) RANGE key * This function is not supported on the 73204 multimeter.

Allows the operator to select the measuring range manually (the display
shows the

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.)

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.

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: 2pcs.).

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.

b)

c)

d) Replace the batteries with new ones and install the

battery holder back into the casing.

Close the casing and fasten it with the three screws.

e)

a)

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:

• 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.
