the measurement, press RANGE button to select a proper range. There are two ranges to choose from:
80.000mV/800.00mV

Connect the black test lead to “COM” terminal and the read test lead to “V Ω Hz” terminal.

Touch the test leads to the test points and read the display on both the primary and secondary display.
Press SELECT Primary display Secondary display

DCmV DCmV
ACmV+Hz ACmV
dBm dBm Hz/ ACmV/ DCmV/ DCmV+ ACmV
NOTE:
1. In dBm measurement mode, the decimal point of dBm is fixed between the second and third digits.
2. When in dBm measurement, the impedance is default at 600Ω. To change the impedance, press RANGE
button to select a proper impedance. The impedance can be chosen from:
4/8/16/32/50/75/93/110/125/135/150/200/250/300/500/600/800/900/1000/1200Ω.
3. In dBm measurement mode, REL
△
, MAX/MIN, AVG, A-H functions are disabled.
4. In milli voltage measurement mode, in order to obtain DC+AC function, the input terminal of ADC does not
employ coupling capacitor. Therefore, never apply a voltage over double value of DC or AC voltage of the
rated value of this range.
4.4 AC/DC Milli Current Measurement (ACmA, DCmA)
WANRNING:

To avoid injury and damage to the meter, never attempt an in-circuit current measurement when the
fuse is blown, or when the voltage between open circuit and the ground is 1000V.

To avoid damage to the meter, check the meter’s fuse before proceeding.

Before current measurement, turn of the circuit power supply, discharge the high voltage capacitance.

Under no circumstances, do not test the voltage when the test leads are plugged in “mA” or “20A”
terminals.

Do not place the probes in parallel with a circuit or
component when the leads are plugged into the current
terminals.
The measurement of AC/DC milli current has three modes:
DCmA, ACmA, DCmA+ACmA, and ACmA +Hz

Set the function key to “mA ” position.

Press SELECT button to select measurement mode.

According to practical demands, press REL
△
, MAX/MIN
and 2nd VIEW buttons to have relative measuring or
record.

The meter is in auto range mode and will automatically
select a most suitable range. To select a range manually for the measurement, press RANGE button to select
a proper range. There are two ranges to choose from: 80.000mA/800.00mA

Connect the black test lead to “COM” terminal and the read test lead to “mA” terminal.

Break the circuit path to be tested. Touch the black test leads to the negative of the break and the red test lead
to the positive of the break. Read the display.

After finishing measurement, disconnect the power supply to the circuit and discharge all high voltage
