DIGITAL AUTO RANGING MULTIMETER
Measuring Current
WARNING!
To avoid damage to the meter, use the proper terminals, function and range for your measurement.
1.
Connect the BLACK test lead (10) to the “COM” jack (6). If the current to be measured is less than 200mA, connect the RED test
lead (10) to the “mA” jack. If the current is between 400mA and 10A, connect the RED test lead (10) to the “10A” jack (4) instead.
2.
Set the range switch to desired current (µA , mA or A ) range. If the current magnitude to be measured is not known
beforehand, set the ranges switch to the highest range position, then reduce it range by range until a satisfactory resolution is
obtained.
3.
Select DC current measurement or AC current measurement with the “ /
/
/~” button (8).
4.
Select auto range or manual range with the “RANGE” button (2). In manual range, if the current magnitude to be measured is
not known beforehand, select the highest range.
5.
Connect test leads in series with the circuit to be measured.
6.
Read the reading on the display. For DC current measurement, the polarity of the RED test lead connection will be indicated as
well.
Note:
When the display shows the over range symbol “OL” a higher range must be selected.
Measuring Resistance
WARNING!
To avoid damage electric shock and/or damage to the instrument, disconnect circuit power and discharge all
high-voltage capacitors before measuring resistance.
1.
Connect the BLACK test lead (10) to the “COM” jack (6) and RED lead (10) to the “VΩ” jack (7).
Note:
The polarity of the RED test lead (10) is positive “+”.
1.
Set the Range Switch (3) to “Ω” range.
2.
Select auto range or manual range with the “RANGE” button (2). In manual range, if the current magnitude to be measured is
not known beforehand, select the highest range.
3.
Connect the test leads (10) across the load to be measured.
4.
Read the reading on the digital display (1).
Note:
a) For resistance measurements greater than 1MΩ, the meter may take a few seconds to stabilise the reading. This is notmal for
high-resistance measurements.
b) When the input is not connected, i.e. at open circuit , the symbol “OL” will be displayed as an over range indicator.
c) Before measuring in-circuit resistance, be sure that the circuit under test has all power removed and all capacitors are fully
discharged.
Continuity Test
WARNING!
To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-
voltage capacitors before testing for Continuity.
1.
Connect the BLACK test lead (10) to the “COM” jack (6) and the RED test lead (10) to the “VΩ” jack (7).
Note:
The polarity of the RED test lead (10) is positive “+”.
2.
Set the Range Switch (3) to “ /
” range.
3.
Press the “ /
/
/~” (8) button to select continuity measurement mode, and the symbol will appear as an indicator.
4.
Connect the test leads (10) across the load to be measured.
5.
If the circuit resistance is lower than 30Ω, the built-in buzzer will sound.
