OPERATION
Before taking any measurements, read the Safety
Information Section. Always examine the instrument for
damage, contamination (excessive dirt, grease, etc.) and
defects. Examine the test leads for cracked or frayed
insulation. If any abnormal conditions exist do not
attempt to make any measurements.
Data Hold
Press [HOLD] button to lock the reading on display, and
release it by pressing the button again.
Manually Selecting Range
The meter also has a manual range mode. In manual
range, you select and lock the meter in a range. To
manually select a range:
Press [RANGE] button to hold the selected range.
Subsequently pressing the [RANGE] button will select
each range in sequence from the lowest to highest
range. Hold the button for 2 seconds to return to the
Autorange Mode.
Voltage Measurements
1. Connect the red test lead to the "V
Ω
" jack and the
black test lead to the "COM" jack.
2. Set the Function/Range switch to the desired Voltage
type (AC or DC) and range. If magnitude of voltage is
not known, set switch to the highest range and reduce
until a satisfactory reading is obtained.
3. Connect the test leads to the device or circuit being
measured.
4. For DC, a (-) sign is displayed for negative
polarity, positive polarity is implied.
Current Measurements
1. Connect the red test lead to the (10A) jack and the
black test lead to the "COM" jack.
2. Set the Function/Range switch to the DC or AC
ranges.
3. Remove power from the circuit under test and open
the circuit path where the measurement is to be taken.
Connect the meter in series with the circuit.
4. Apply power and read the value from the display.
Resistance Measurements
1. Set the Function/Range switch to the desired
resistance range.
2. Remove power from the equipment under test.
3. Connect the red test lead to the "V
Ω
" jack and the
black test lead to the "COM" jack.
4. Connect the test leads to the points of measurements
and read the value from the display.
Diode Tests
1. Connect the red test lead to the "V" jack and the black
test lead to the "COM" jack.
2. Set the Function/Range switch to the "
" position.
3. Turn off power to the circuit under test. External
voltage across the components causes invalid
readings.
4. Touch probes to the diode. The forward-voltage drop
is about 0.6V (typical for a silicon diode).
5. Reverse probes. If the diode is good, "OL" is
displayed. If the diode is shorted, "0.00" or
another number is displayed.
6. If the diode is open, "OL" is displayed in both
directions.
7. Audible Indication: Less than 0.25V.
Continuity Measurements
1. Set the Funtion switch to the
position.
2. Turn off power to the circuit under test. External
voltage across the components causes invalid
reading.
3. Connect the test leads to the two points at which
continuity is to be tested. The buzzer will sound if the
resistance is less than approximately 25
Ω
.
Auto Power off
1. Auto power off: approx. 10 minutes.
2. After auto power off, press any button to restart
the meter, and the reading will be maintained in the
display.
Cancellation of Auto Power Off Feature:
Press and hold the (RANGE) button while rotating
function switch from off to any position. The auto power
off feature is disabled. Note “APO” annunciator is missing
from the LCD.
MAINTENANCE
Battery Replacement
Power is supplied by a 1.5 volt battery x2 (R03/SIZE
AAA). The "
" appears on the LCD display when
replacement is needed. To replace the battery, remove
the 2 screws from the back of the meter and lift off the
battery cover. Insert new batteries, observing correct
polarity.
WARNING
Remove test leads before changing battery,
fuse or performing any servicing.
Fuse Replacement
If no current measurements are possible, check for a
blown overload protection fuse. For access to fuses,
remove the four screws from the back of the meter and lift
off the front case. Replace F1 only with the original type
10A/500V, fast acting ceramic fuse.
Cleaning
Wipe the case with a damp cloth and mild detergent. Do
not use abrasives or solvents. Dirt or moisture in the
terminals can affect readings.
