6.8 Measurement of capacitance
WARNING:
Risk of electric shock. Disconnect the power supply from the tested capacitor and discharge
all capacitors before any starting capacity measurements.
To perform the measurement:

set the rotary switch at
Ω
CAP ,

connect black test lead to COM terminal and red test lead to V
Ω
CAP Hz% Temp terminal,

select MENU and use arrows and F1 F2 F3 F4 buttons to set CAP ,

contact the probe tips to the tested capacitor,

read the measurement result on the display,

after completing the measurements, remove test leads from the terminals of the meter.
6.9 Current measurement up to 10 A
NOTE
Do not make current measurements of 20 A DC and AC for longer than 30 seconds. Exceeding
this time may cause damage to the meter and/or test leads.
To perform the current measurement:

set the rotary switch at 10A ,

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 10A 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,

contact the probes to the poles of the tested object;

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 of the circuit,

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.
6.10 Current measurement up to 500 mA
To perform the current measurement:

set the rotary switch at mA ,

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,
