Relative Button
The relative measurement feature allows you to make measurements relative to a stored reference
value. A reference voltage, current, etc. can be stored and measurements made in comparison to that
value. The displayed value is the difference between the reference value and the measured value.
1.
Perform any measurement as described in the operating instructions.
2. Press the RELATIVE button to store the reading in the display and the “REL” indicator will
appear on the display.
3. The display will now indicate the difference between the stored value and the measured value.
4. Press the RELATIVE button to return to normal operation.
Backlight Button
1.
Press the BACKLIGHT button for 2 seconds to switch the light ON.
2. Press BACKLIGHT button again to exit the light mode.
Hz/% Duty Button
Press Hz/Duty Button to choose Frequency or Duty Cycle in the range of Frequency; Press
Hz/%Duty Button to measure Frequency or Duty Cycle while measures voltage or Current, the
Voltage/Current requirement and range of Frequency (see the following table), press Hz/%Duty
Button to return to measurement of Voltage or Current.
Note: The above data is only for reference.
DC VOLTAGE MEASUREMENTS
CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF.
Large voltage surges may occur that can damage the Multimeter.
1.
Set the function switch to the V DC position (“mV” will appear in the display).
2. Insert the black test lead banana plug into the negative (COM) jack and the red test lead
banana plug into the positive (V) jack.
3. Touch the test probe tips to the circuit under test. Be sure to observe the correct polarity (red
lead to positive, black lead to negative).
4. Read the voltage in the display. The display will indicate the proper decimal point and
value. If the polarity is reversed, the display will show (-) minus before the value.
AC VOLTAGE MEASUREMENTS
WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts
inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a
result, the reading may show 0 volts when the outlet actually has voltage on it. Make sure the probe
tips are touching the metal contacts inside the outlet before assuming that no voltage is present.
CAUTION: Do not measure AC voltages if a motor on the circuit is being switched ON or OFF.
Large voltage surges may occur that can damage the Multimeter.
2. Press the RELATIVE button to store the reading in the display and the
"REL" indicator will appear on the display.
3. The display will now indicate the difference between the stored value
and the measured value.
4.
Press the RELATIVE button to return to normal operation.
BACKLIGHT BUTTON
1.
Press the BACKLIGHT button 2 seconds to display light ON
2.
Press BACKLIGHT button again to exit the light mode.
Hz/%duty BUTTON
Press Hz/Duty Button to choose Frequency or Duty Cycle in the range of
Frequency; Press Hz/%Duty Button to measure Frequency or Duty Cycle
while measures voltage or Current, the Voltage/Current requirement and
range of Frequency see the following form, press Hz/%Duty Button to
return to measurement of Voltage or Current.
