
Direct Current (DC): the pin of black probe should contact negative pole of the circuit, while
the pin of red probe should contact positive pole,

turn on the power supply of the circuit,

read the measurement result on the display,
after completing the measurements, remove test leads from the terminals of the meter.
6.11 Current measurement up to 5000
µA
To perform the current measurement:

set the rotary switch at
μA
,

select MENU and use arrows and F1 F2 F3 F4 buttons to set the measurement of:

direct current voltage DC (default setting),

alternating current voltage AC ,

connect black test lead to COM terminal and red test lead to
µA/mA
terminal,

remove power supply from the measured circuit and then connect the meter in series to the cir-
cuit at the point where the current is to be measured,

Direct Current (DC): the pin of black probe should contact negative pole of the circuit, while
the pin of red probe should contact positive pole,

turn on the power supply of the circuit,

read the measurement result on the display,

after completing the measurements, remove test leads from the terminals of the meter.
6.12 Measurement of current loop 4~20mA %
To perform the measurement:

set the rotary switch at 4~20mA%,

select MENU and use arrows and F1 F2 F3 F4 buttons to set 4-20 mA ,

connect black test lead to COM terminal and red test lead to
µA/mA
terminal,

turn on the meter in series with the circuit under test;

the meter will display loop current as % value with:

0 mA = -25%,

4 mA = 0%,

20 mA = 100%,

24 mA = 125%.
