MEASURING METHOD
1. DC VOLTAGE (DCV)
1) Set the position of rotary switch from OFF to DCV (… sign will be displayed).
2) According to the drawings,
red test lead contact to
○
＋
polarity
battery etc. and black one to
○
－
.
3) Read the voltage value on the display. (Can measure up to 500V automatically).
2. AC VOLTAGE (ACV) TRUE RMS
1)
Set the rotary switch position to V and press once the select key to chose
「～」
.
2)
According to the drawings, insert
the test leads to the outlet , etc. to
be measured. (In case of ACV measurement,
red or black test lead and polarity of
○
＋
or
○
－
are no concern).
3)
Read the voltage value on the display.
(Can measure up to 500V automatically).

WARNING
1. Do not apply the input signal more than max. rated input voltage (500V).
2. During measurement, do not change rotary switch position.
3. Do not hold and or touch the nearer position of test leads to the tip over collar
during measurement.
4. POSSIBLE ELECTRIC SHOCK
Confirm that there is no damage in the isolated wire of test leads before
connecting. In case of out of order, stop the operation and repair them.
5. POSSIBLE DAMAGE & FIRE HAZARD
Connect test leads firmly, the wrong connection may cause spark.
3. RESISTANCE (
