WARNING
To avoid electric shock!
• Do not use deteriorated or damaged testing leads. Check testing leads before use.
• 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 re-
place 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.
Measurement Category (CAT.) Maximum Input Voltage
II
III
Measurement category Description
IM3E-2006.2
For measurements performed on circuits
1 CAT.1
not directly connected to MAINS.
2 CAT.2 For measurements performed on circuits
directly connected to the low voltage installation.
For measurements performed
3 CAT.3
in the building installation.
For measurements performed
4 CAT.4
at the source of the low-voltage installation.
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 read-
ing or errors.
• Do not wipe the instrument using any organic solvent such as benzine or paint thinner.
Otherwise, the front panel may be damaged or discolored. When cleaning the instru-
ment, 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.
• / : In this mode, the button selects between the resistance measurement and continu-
ity test.
• : In this mode, the button adjusts the stray capacitance of the testing leads and the
multimeter itself to zero.
(The display shows the
• A/mA/A: In this mode, the button selects between the DC and AC modes.

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
bol).
To return to the normal auto-ranging mode, hold down this button for at least one second until
the display shows "AUTO."

Measuring Instructions
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 measure-
ment.
• Temporarily remove the testing leads from the device under test before operating the
function switch.
