Unit of Measure Multipliers
For your reference, the following symbols are often used to
make measurement easier:

M mega x 1,000,000
k kilo x 1,000
m milli ÷ 1,000
µ micro ÷ 1,000,000
Auto Power Off (APO)
The APO sign on the LCD panel indicates the meter is working
in the Auto Power Off mode. If the meter idles for more than 30
minutes, the meter automatically turns the power off. When this
happens, the state (non-logic measurement) of the meter is
saved, the meter can be turned back on by pushing any key
switch or changing the rotary switch. The meter will give an
alarm 15 seconds before the meter automatically turns the
power off. To disable the auto power off function, power up the
meter while pressing either the range or Hz switch.

AC Conversion Type: AC conversions are ac-coupled, true rms
responding, calibrated to the rms value Sine wave input.
Input and Impedance: 10MΩ less than 100 PF.
Crest Factor: +1.5% additional error for C.F. from 1.4 to 3
+3.0% additional error for C.F. from 3 to 4
To Measure True RMS AC Voltage:
1. Plug the black test lead into the COM port and the red test lead
into the VΩH port.
2. Set the rotary switch to the V position.
3. Push the blue button until
AC is shown on the display.
4. Connect the meter in parallel with the load or circuit.
5. Measure AC Voltage.
