MEASURING AC VOLTAGE

•
Beware of electrocution.
•
Pay special attention to avoid electric shock when measuring high voltage.
•
Do not input voltage, which is more than 750V rms AC.
•
Plug the black test lead into the COM jack and the red test lead
into the INPUT jack.
•
Set the rotary selector to the V~ position to make the meter
enter into AC V range.
•
Connect the test leads to the voltage source or load terminals
for measurement.
•
Take the reading on the LCD.
Note: "
" means the maximum input voltage is 750V rms AC.
•
If the test result is more than 750V rms AC, the "OL" symbol
will be displayed on the LCD and the build-up buzzer will
sound.

MEASURING DC VOLTAGE

•
Beware of electrocution.
•
Pay special attention to avoid electric shock when measuring high voltage.
•
Do not input voltage, which is more than 1000V DC.
•
Plug the black test lead into the COM jack and the red test
lead into the INPUT jack.
Set the rotary selector to the V
•
•
Connect the test leads to the voltage source or load terminals
for measurement.
•
Take the reading on the LCD. The polarity symbol denotes the
polarity of the end connected by the red test lead.
Note: At small voltage range, unsteady readings will appear before
the test leads contact the circuit. This is normal because the meter
is highly sensitive. When the leads contact the circuit the true
readings will be shown.
•
"
" means the maximum input voltage is 1000V DC.
•
If the test result is more than 1000V DC, the symbol "OL" will
be displayed on the LCD and the builld-up buzzer will sound.
MEASURING FREQUENCY BY A RANGE (FROM CURRENT CLAMP)
•
Beware of electrocution.
•
Ensure that the test leads are disconnected from the meter before making
current clamp measurements.
Set the rotary selector to the A range (A~ or A
•
•
Press the trigger to open the jaw and fully enclose only one conductor.
•
Press the "Hz/%" button to switch to the frequency measurement.
•
Take the reading on the LCD.
Note: Do not put more than one cable into the jaw during testing, otherwise the
