jack (COM) and the red test lead banana plug into the
positive (+) jack (
).
3.
Touch the test probe tips to the circuit or wire you wish
to check.
4.
If the resistance is less than approximately 50
, the
audible signal will sound. The display will also show the
actual resistance.
DIODE TEST
WARNING:
To avoid electric shock, do not test any
diode that has voltage on it.
1. Set the function switch to position.
3. Insert the black test lead banana plug into the negative (-)
jack (COM) and the red test lead banana plug into the
positive (+) jack (
).
4.
Touch the test probe tips to the diode or
semiconductor junction you wish to test. Note the meter
reading
5. Reverse the probe polarity by switching probe position.
Note this reading.
6. The diode or junction can be evaluated as follows:
A. If one reading shows a value and the other reading
shows “1”, the diode is good.
B. If both readings show “1”, the device is open.
C. If both readings are very small or 0, the device is
shorted.
NOTE:
The value indicated in the display during the diode
check is the forward voltage.
CAPACITANCE MEASUREMENTS
WARNING:
To avoid electric shock, disconnect power
to the unit under test and discharge all capacitors before
taking any capacitance measurements. Remove the
batteries and unplug the line cords.
1.
Set the function switch to the CAP position.
2.
Insert the black test lead banana plug into the negative (-)
jack (COM) and the red test lead banana plug into the
positive (+) jack (CAP).
3.
Touch the test leads to the capacitor to be tested.
The display will indicate the proper decimal point,
value
REPLACING THE BATTERY
WARNING
: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the
battery door.
1.
When the batteries become exhausted or drop below
the operating voltage, “BAT” will appear in the
right-hand side of the LCD display. The battery should
be replaced.
2.
Follow instructions for installing battery. See the
Battery Installation section of this manual.
3. Dispose of the old battery properly.
WARNING:
To avoid electric shock, do not operate your
meter until the battery door is in place and fastened
securely.
BATTERY INSTALLATION
WARNING
: To avoid electric shock, disconnect the
test leads from any source of voltage before
removing the battery door.
1.
Disconnect the test leads from the meter.
2.
Open the battery door by loosening the screw using a
Phillips head screwdriver.
3.
Insert the battery into battery holder, observing the
correct polarity.
4.
Put the battery door back in place. Secure with the one
screw.
WARNING:
To avoid electric shock, do not operate the
meter until the battery door is in place and fastened
securely.
NOTE
: If your meter does not work properly, check the
fuses and battery to make sure that they are still good and
that they are properly inserted.
REPLACING THE FUSES
WARNING
: To avoid electric shock, disconnect the test
leads from any source of voltage before removing the
back cover
1. Disconnect the test leads from the meter and any item
under test.
2. Open the
back cover
by loosening the screw on the
back
cover
using a Phillips head screwdriver.
3. Remove the old fuse from its holder by gently pulling it
