4) Press “
∆
” button, you can use the relative function to eliminate the zero error.
5) Connect the probes across capacitor to be tested.
Note: When testing 400
μ
F / 4000
μ
F capacitor, note that there will be approx. 30 sec time lag.
Caution: Ensure that the circuit to be tested is "dead".
Max. input over-load: 250V RMS. and<10sec.
2.8 Frequency measurement
1) Connect the black test lead to "
COM
" socket and red test leads to the "
FREQ
" socket.
2) Set the selector switch to “
DUTY
FREQ
” position.
3) Connect the probes across the source or load under measurement.
2.9 Temperature measurement
1)
Set the selector switch to the ”
TEMP °C/°F
” range and connect the k type thermocouple’s
black ( or “-“ terminal ) test lead to “
COM
” socket and red ( or “+“ terminal ) test lead to the
"
TEMP
" socket and read value on display screen. The range of TP-02 thermocouple is
-50~+700°C ( -58 ~1292°F).
2)
Press
SELECT
button to switch °C or °F display.
3)
Opening the input will display the temperature at the meter terminals by the internal built-in
sensor.
2.10 Auto Power Off
When the meter has been turned on about 15 minutes without any action from the users, the
