Measuring Resistance, Continuity and Diode

W

Warning

• To avoid false readings that can lead to electrical shock and injury, de­energize the circuit before taking the measurement.

• To avoid electrical shock when testing resistance/continuity/diode in a
circuit, make sure the power to the circuit is turned off and all capacitors
are discharged. Use DC voltage function to check the capacitors are
discharged.

1. Connect the black test lead to the COM terminal and the red test lead
to the Ω terminal.

2. Turn the rotary switch to

3. Press SELECT button for desired measurement function.

4. Connect the probes across the circuit or component to be tested.

Resistance measurement: The resistance reading appears on the

display. If the circuit is open or resistance exceeds the Meter’s range,
the display reads “OL”.

Continuity measurement: If the circuit is shorted, the Meter beeps and

shows a reading ≤ 10 Ω. (Beeper ON ≤ 10 Ω, OFF > 250 Ω) If the circuit is
open or resistance exceeds the Meter’s range, the display reads OL.

Testing diode: When testing diode, normal forward voltage drop

(forward biased) for a good silicon diode is between 0.400V to 0.900V.
A reading higher than that indicates a leaky diode (defective). A zero
reading indicates a shorted diode (defective). Display reads “OL”
indicates an open diode (defective). Reverse the test leads connections
(reverse biased) across the diode. The display reads “OL” if the diode
is good. Any other readings indicate the diode is resistive or shorted
(defective).

Measuring Capacitance and Temperature

W

Warning

To avoid electrical shock and injury:

• When testing capacitor in a circuit, make sure the power to the circuit is
turned off and all capacitors are discharged.

• When measuring temperature, DO NOT apply the temperature probe to
any live conductive parts.

Capacitance

1. Turn off circuit power, then disconnect and discharge the capacitor
before measuring capacitance.

2. Connect the black test lead to the COM terminal and the red test lead
to the

3. Turn the Meter’s rotary switch to capacitance

4. Connect the probes across the capacitor to be tested. When measuring,
be sure to note the correct polarity of the capacitor.

Temperature

The Meter measures temperature in either Celsius (°C) or Fahrenheit (°F).

1. Connect the banana plug type-K temperature probe to the Meter’s
input terminal noting correct polarity of the probe.

2. Turn the rotary switch to

3. Press SELECT button to select °C or °F. The display reflects the chosen

and modes.

: Hi-sensitivity mode for checking phase rotation of Motors detects

relatively low signal outputs generated spinning a motor shaft,.

: Normal-sensitivity mode for identifying phase sequence of 3-phase

MAINS supply.

W

Caution

Correct rotation detection relies on solid signal connection to all three test
lead terminals simultaneously. Any loose connection will lead to detection
failure and false indication. To verify signal connection and the correct
rotation indication, swap any of two signal connections l to check for

indication of reverse movement.

Hi-sensitivity mode for Motors:

Connect the test lead L1/L2/L3 to the motor connections by using probes
and/or alligator clips. Be sure the power supply is removed from the motor.
From the perspective of looking down the shaft of the motor, speedspin
it clockwise to generate sufficient signal strength for rotary detection. If
the meter indicates a clockwise movement, the motor leads connected to
L1, L2 and L3 of the meter are L1, L2 and L3 (also known as R, S and T),
respectively. If the meter indicates a counter-clockwise movement, swap any
of two motor connections and retest.

14

Normal mode

Connect the test lead L1/L2/L3 to the 3-phase mains circuit by using probes
and/or alligator clips. If the meter indicates a clockwise movement, the
phases connected to L1, L2 and L3 of the meter are L1, L2 and L3 (also
known as R, S and T), respectively. If the meter indicates a counter-clockwise
movement, swap any two connects between the meter and phases. Then
retest. Connecting the above mentioned L1, L2 and L3 of a motor and that
of the MAINS respectively should get a clockwise motor movement.

for the MAINS circuit:

Using the Beeper feature on

Press and hold the REC button while turning the rotary switch to
to enable the beeper, the display shows “Enbp”. When making rotary
measurement, if the rotary indication segments indicate a clockwise
movement, the beeper sounds a single long beep per segment cycle. If the
rotary indication segments indicate a counter clockwise movement, the
beeper sounds 3 short beeps per segment cycle.

& mode:

Auto Power Off

The meter turns off if there is no button pushed, rotary function switch
operation for 32 minutes and/or no specified activities below, where
applicable:

1.) Significant measuring readings of above 8.5% of ranges

2.) Non-OL readings for Resistance, Continuity or Diode function

3.) Non-zero readings for Hz function

4.) Significant movement indication as in Phase Rotation functions

The meter will not enter auto power off mode when under normal
measurements. To turn the meter back on, press the SELECT button and
release, or turn the rotary switch off and on to restart the meter.

MAINTENANCE AND REPAIR

If the Meter fails to operate, check battery, test leads, etc., and replace as
necessary.

Double check the following:

1. Replace the fuse or battery if the meter does not work.

2. Review the operating instructions for possible mistakes in operating
procedure.

20

Except for the replacement of the battery, repair of the meter should be
performed only by a Factory Authorized Service Center or by other qualified
instrument service personnel.

The front panel and case can be cleaned with a mild solution of detergent
and water. Apply sparingly with a soft cloth and allow to dry completely
before using. Do not use aromatic hydrocarbons, gasoline or chlorinated
solvents for cleaning.

BATTERY REPLACEMENT

When battery voltage drops below the value required for proper operation,
the battery symbol ( ) appears.

W

Warning

To avoid shock, injury, or damage to the Meter, disconnect test leads before
opening case.

Replacing BATTERY follow below steps:

1. Disconnect the test lead probe from measuring circuit.

2. Turn the Meter to OFF position.

3. Remove the screws from the battery cover and open the battery cover

4. Remove the batteries and replace with 1.5V AA Size (IEC R6). Observe
correct polarity when installing the batteries.

5. Put the battery cover back and re-fasten the screw.
Battery: 2 x 1.5 V AA (IEC R6)
