WARNING
Do not make measurements of power lines carrying more than 250V.
IN SOME CASES, POWER LINES MAY CARRY VOLTAGE SPIKES OF
SEVERAL TIMES OF THE NORMAL SUPPLY VOLTAGE. THIS
INSTRUMENT SHOULD NOT BE USED TO MEASURE POWER LINES.
* The term of “POWER LINE” means the electrical circuit providing the
power to factories, buildings, and etc.

WARNING
POSSIBLE ELECTRICAL SHOCK. Do not make measurements if the case
is damaged or the rear case is removed. Remove all electrical inputs before
removing the rear case.

CAUTION
To avoid damage to the tester, disconnect test leads before changing
functions. Do not exceed the maximum input limits.
4-3. Measurement of Resistance and Continuity Check
①
Set the power switch to "ON" position.
②
Connect the plug of red test lead into
the “
Ω
” terminal and the plug of black
test lead into the “COM” terminal.
③
Set the range selector switch to “
Ω
” or
“
･
)
)
)
2K
Ω
” range.
④
Contact the tips of the teat leads to the
circuit under test.
⑤
Read the resistance value in the display.
In continuity check, if the circuit under test has a resistance of less than
approximately 300
Ω
, the continuity beeper will sound.

CAUTION
Be sure all voltage is turned OFF in the circuit before making resistance
measurement.
