DC CURRENT MEASUREMENTS
CAUTION:
Do not make current measurements on the 10A scale for longer than 10
seconds. Exceeding 30 seconds may cause damage to the meter
and/or the test leads.
1. Insert the black test lead banana plug into the negative COMjack.
2. Insert the red test lead into:
For measurements up to 200 mA - "V? mA" input
For measurements exceeding 200mA - 10ADC input.
The device must be set to DCA range. Test probes need to be applied
serially.
RESISTANCE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect power to the unit under test and
discharge all capacitors before taking any resistance measurements.
Remove the battery and unplug the line cords.
1. Set the function switch to the highest position.
2. Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive jack.
3. Touch the test probe tips across the circuit or part under test. It is
best to disconnect one side of the part under test so the rest of the
circuit will not interfere with the resistance reading.
4. Read the resistance in the display and then set the function switch to
the lowest position that is greater than the actual or any anticipated
resistance.
HFE
1. Set the device to "hFE" position.
2. Place the tips of the tested transistor into the "NPN PNP" slot
according to the markings.
3. An approximate hFE value will be displayed for Uce = 2.8V and IB=
10
ì
A.
CONTINUITY CHECK
WARNING:
To avoid electric shock, never measure continuity on circuits or wires
that have voltage on them.
1. Set the function switch to the position.
2. Insert the black lead banana plug into the negative COMjack.
Insert the red test lead banana plug into the positive "V? mA" jack.
3. Touch the test probe tips to the circuit or wire you wish to check.
4. If the resistance is less than approximately 30? , the audible signal
will sound.
DIODE TEST
1. Insert the black test lead banana plug into the negative COM jack
and the red test lead banana plug into the positive V? mA jack.
2. Turn the rotary switch to the 2000 ? position.
3. Touch the test probes to the diode under test. Connect black wire
with anode, and red with cathode.
