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.

CAUTION
• Do not use the multimeter near noise-emitting equipment or where there may
be a sudden temperature change. Otherwise, the instrument may produce an
unstable reading or errors.
• Do not wipe the instrument using any solvent (chemicals) such as benzine or
paint thinner. Otherwise, the front panel may be damaged or discolored.
When cleaning the instrument, use a dry cloth.
• Do not leave the multimeter exposed to direct sunlight or in a hot and humid
location such as the inside of a car, for any prolonged length of time.

2) SELECT key (73202/03) or
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
• 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 symbol).

Measuring Instructions
CAUTION
To avoid damage to Instrument or equipment.
• Before starting measurement, check to which mode the function switch is set
and make sure the testing leads are plugged into the terminals for the desired
mode of measurement.
• Temporarily remove the testing leads from the device under test before
operating the function switch.
