Prokit's Industries 3PK-9912 - Manual (Page 9)

As the jaw core may remain some magnetic force after using for awhile. If the
display can not reach “0”, taking following process to correct it please:
1. Open the jaws several times.
-6-
2. Adjusting the DCA ZERO knob, making the display is “0”.
3. Then work again.
RESISTANCE MEASUREMENT
1.
2.
3.
4.
Connect the red test lead to “
Ω” jack and black test lead to the “COM”
jack (The polarity of red lead is positive “+”).
Set the rotary switch at desired ” Ω” range position.
Connect test leads across the resistor to be measured and read LCD
display.
If the resistance being measured is connected to a circuit，turn off power
and discharge all capacitors before applying test leads.
NOTE:
1. If the resistance being measured exceeds the maximum value of the
range selected or the input is not connected, an overrange indication
“OL”will be displayed.
2.
3.
4.
When checking in-circuit resistance, be sure the circuit under test has all
power removed and that all capacitors have been discharged fully.
For measuring resistance above 1M
Ω, the meter may take a few
seconds to get stable reading. This is normal for high resistance
measurements.
When the input is not connected, i.e. at open circuit, the figure “OL” will
be displayed for the overrange condition.
MEASURING FREQUENCY
1.
2.
3.
4.
Connect the red test lead to “VHz” jack and the black test lead to the
“COM” jack.
Set the rotary switch at desired kHz position.
Connect test leads across the source or load being measured.
Read frequency value on the LCD display.
NOTE:
