Current is the flow of electrons through a conductor.
The Meter's DC current ranges are 2.0000mA,
200.00mA and 10.000A;AC current ranges are
2.0000mA, 200.00mA and 10.000A.
To measure current:
1. Turn off the power of the measured circuit.
Discharge all the high voltage capacitors.
2. Set the rotary switch to the proper range.
3. Connect the black test lead to the COM terminal
and the red test leads to the mA terminal for a
maximum of 200mA. For a maximum of 10A, move
the red test lead to the 10A terminal.
4. Break the circuit path to be tested.
Connect the black test lead to the more negative
side of the break; connect the red test lead to the
more positive side of the break. (Reversing the
leads will give a negative reading, but will not
damage the Meter.)
5. Turn on the power of the measured circuit, and
then read the display. Be sure to note the
3.2.6 Transistor measurement
To avoid electrical shock and/or damage to the
instrument, do not apply more than 250Vdc or
250Vac rms between the hFE terminal and the
COM terminal.
1. Set the rotary switch to hFE range.
2. Connect the “com” plug and “+” plug of the special
multi-function socket to the COM and hFE terminals.
3. Determine whether the transistor to be tested is
NPN or PNP type and locate the Emitter, Base and
Collector leads.
4. Insert leads of the transistor into proper holes of the
special multi-function socket.
5. The meter will show the approx. hFE value.
3.2.8 Current measurement
To avoid damage to the Meter or injury if the fuse
blows, never attempt an in-circuit current
measurement where the open-circuit potential to
earth is greater than 250V.
To avoid damage to the meter, check the meter's
fuse before proceeding. Use the proper terminals,
function, and range for your measurement. Never
place the test leads in parallel with a circuit or
component when the leads are plugged into the
current terminals.
3.2.7 Frequency measurement
Do not measure Frequency on high voltage (>380V)
to avoid electrical shock hazard and/or damage to
the instrument.
Frequency is the number of cycles a voltage or current
signal completes each second.
To measure frequency:
1. Set the rotary switch to 20kHz range.
2. Connect the black and red test leads to the COM
and Hz terminals respectively.
3. Connect the test leads to the circuit being measured
4. Read the displayed value.
