Functions

Auto Power Save Function

• This function automatically switches to the power save state
when 30 minutes have elapsed since the last operation.

• The auto power save function is activated automatically
when the power is turned on. To restore from the auto power
save state, turn the function switch to the OFF position once.

To avoid battery depletion, turn the function selector OFF after
use (the Auto Power Save feature consumes a small amount of
current).

To Disable Auto Power Save

1.Move the function switch from the OFF position to the
(continuity check) position before all display segments
appear.

2.While all display segments appear (about one second ), move
the function switch from to . APS
and the Auto Power Save function is disabled. Turning the
function switch momentarily OFF and then back on reacti­vates Auto Power Save.

 OFF is displayed,

Auto-range Function

When measuring a DC voltage [ V], AC voltage [ V], or re­sistance [], the measurement range is automatically set to the
most appropriate range. Manual range setting is not possible.

Overflow Display

When the input exceeds the measurement range, "OF" is dis-
played.

Names and Functions of Parts

Removable sleeves can be attached to the metal
pins at the ends of the test leads. To prevent a short
circuit accident, be sure to use the test leads with
the sleeves attached when performing measure­ments in the CAT III measurement category. Remove
the sleeves from the test leads when performing
measurements in the CAT II measurement category.
For details on measurement categories, see "Mea­surement categories" in the instruction manual.

• The tips of the metal pins are sharp, so take care not to in jure
yourself.

• When performing measurements with the sleeves attached,
be careful to avoid damaging the sleeves.

• If the sleeves are inadvertently removed during measure­ment, be especially careful in handling the te st leads to avoid
electric shock.

Measurement Method

Observe the following precautions to avoid electric
shock.

• Always verify the appropriate setting of the function
selector before connecting the test leads. Disconnect
the test leads from the measurement object before
switching the function selector.

• Never apply voltage to the test leads when the Resis­tance measurement, Continuity check functions are
selected. Doing so may damage the instrument and
result in personal injury. To avoid electrical accidents,
remove power from the circuit before measuring.

• The maximum input voltage is 500 V DC/ACrms or 3 x

•V/Hz. Attempting to measure voltage in excess of
the maximum input could destroy the instrument and
result in personal injury or death.

• To avoid electrical shock, be careful to avoid shorting
live lines with the test leads.

• For safety, test lead connections must always be
made at the secondary side of a circuit breaker.

• The maximum rated voltage between input terminals
and ground is CAT III (300 V), CA T II (600 V). Attempt­ing to measure voltages exceeding 450 V with respect
to ground could damage the instru ment and result in
personal injury.

Pre-Operation inspection

To avoid the possibility of electric shock or incorrect measure­ment, check the following items before using the instrument.
If the operation check reveals any a bnormalities, stop t he check
