3. Press the POWER switch to ON, connect the black clip to a
measuring point on the measurement object, and apply the tip of
the red test rod to another measuring point. The LCD will show the
measurement voltage value.
4. After measurement, press the POWER switch again to OFF or set
the function switch to OFF.
WARNING
1. The maximum allowable input voltage of the DCV range is
750 V. Never apply a higher voltage than this.
2. DC Voltages higher than 60 V are hazardous to the human body.
Be very careful during measurement.
3. Never attempt to change the function switch position during
measurement.
4. Never touch the device with a wet hand.
1. Set the function switch to appropriate range, but if the voltage to be
measured is uncertain, set it to DCV 0-750 V range.
2. Same as the ACV measurement, connect both black & red plugs to
measurement terminals.
3. Press the POWER switch to ON, connect the black clip to the earth
line (lower voltage side) and red point on the measurement object
(higher voltage side), the LCD will show the measurement voltage
value.
4. If the measured value is less than 20 V, then turn off the device, and
make measurement again by setting the function switch to DCV
0-20 V range.
5. After measurement, press the POWER switch again to OFF or set
the function switch to OFF.
