4. Connect the test leads to the resistance in the circuit
being measured.
5. When the test lead to the circuit is below approx. 30,
a continuous beeping will indicate it.
Note:
Continuity test is available to check open/short of the
circuit.
3.2.5 Capacitance measurement
To avoid electrical shock and/or damage to the
instrument, disconnect circuit power and
discharge all high-voltage capacitors before
measuring capacitance. Use the dc voltage
function to confirm that the capacitor is
discharged.
Capacitance is the ability of a component to store an
electrical charge.
The unit of capacitance is the farad (F). Most capacitors are
in the nanofarad to microfarad range.
The Meter's capacitance ranges are 20.00nF, 200.0nF,
2.000F, and 200.0F.
To measure capacitance:
1. Set the rotary switch to proper range.
2. Connect the black and red test leads to the COM and
terminals respectively
3. Connect the test leads to the capacitor being measured
and read the displayed value.
Some tips for measuring capacitance:
The meter may take a few seconds to stabilize reading.
This is normal for high capacitance measuring.
To improve the accuracy of measurements less than 20nF,
subtract the residual capacitance of the Meter and leads.
3.2.6 Inductance measurement
The unit of Inductance is the farad (H). The Meter's
Inductance ranges are 20.00mH, 200.0mH, 2.000H, and
20.00H.
To measure Inductance:
1. Set the rotary switch to proper range.
2. Connect the black and red test leads to the COM and
LX terminals respectively
3. Connect the test leads to the Inductance being
measured and read the displayed value.
3.2.7 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 at test
condition of base current 10μA and Vce 2.8V.
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.
