new “max or min” occurs.
4.5.2. Press the MAX/MIN
key and a blinking “MAX MIN” will appear. The meter
will display the present reading, but will continue to update and store the max
and min readings.
To exit MAX/MINmode press and hold the MAX/MIN key for 2 seconds.
PeakHold button
The Peak Hold function captures the peak AC voltage or current.
The meter can capture negative or positive peaks as fast as
1 millisecond in duration.
1. Turn the function switch to the A or V position.
2.
Press the PEAK button, “Peak MAX” will display.
3. The display will update each time a higher positive peak occurs.
4.
Press the PEAK button again, “Peak MIN” will display. The display will now
update and indicate the lowest negative peak.
5.
To return to normal operation, press and hold the PEAK button until the Peak
MIN or “Peak MAX” indicator switches off.
Backligh
button
1. Press the BACKLIGHT button to turn the backlighting ON.
2. Press the BACKLIGHTbutton again to turn the backlighting OFF.
Meter functions
1. Voltage(V)
The meter will automatically select the best voltage(V) range.
Press
“AC/DC” button to select AC or DC.
Insert:
*black lead in COM terminal.
*red lead in V/
Ω
/
RPM terminal .
Touch the Black probe to the circuit coming from the power source.
Touch the Red probe to the circuit coming from the power source .
IMPORTANT: voltage must be measured in parallel (red probe measuring
circuit from power source).
Accuracy
Selection of a lower range will move the decimal point one place and
increase the accuracy of the reading .An OL(Over limit) display means the
range is too low .select the next higher range.
2. Resistance(
Ω
)
IMPORTANT:
if you are testing an application that has capacitors in the circuit.
be sure to turn the power OFF on the test circuit and discharge all capacitors.
Accurate measurement is not possible if external or residual voltage is present.
Select the resistance
(
Ω
) setting with the
rotary switch.
Select the
resistance
(
Ω
) range with the
button labeled
“RANGE ” if a more
accurate measurement is desired.
Insert:
*Black lead in COM terminal.
*Red lead in
V
/
Ω
/
RPM
terminal.
Touch the test lead probes across the
resistor to be tested.
3. Audible Continuity
IMPORTANT: Turn the power OFF on the test circuit
Select the
range with the rotary
switch .
Press
“
” button to select
Audible
continuity.
Insert:
*Black lead in
COM
terminal.
*Red lead in
V/
Ω
/
RPM
terminal.
Connect one test probe to each end of
the circuit to be tested.
*circuit complete. The meter will
