6. Operating Instructions
Important: Before operating this product, read and
understand all the safety instructions listed in this
manual.
Important: Inspect the device for signs of damage,
particularly the probes and insulated cables. Replace
faulty leads immediately.
For each measurement type, connect the positive probe
(7) to the voltage, resistance and amperage probe
terminal (8), and connect the negative probe (5) to the
common earth probe terminal (1).
If the display gauge needle does not move during
operation, check the polarity of the probes at the
component contacts and the device terminals.
6.1 Installing the Battery
This product requires 1 x 1.5V AA battery (not supplied)
to operate.
WARNING! To prevent an electric shock, the test
cables MUST be disconnected from the device
before accessing the battery.
1. Remove the screw on the back of the device to loosen
the battery compartment cover.
2. Separate the front of the device from the rear casing
at the divide around the tapered edge of the housing.
3. Install the battery between the two contacts above
the circuit board, observing the polarity indicated.
4. Reassemble the device housing and tighten the rear
screw securely.
6.2 The Function Dial
Use the function dial (3) to select the value that most
accurately represents the anticipated measurement
range from the appropriate measurement type. If the
value to be measured is not known, set the function dial
to the highest available range and reduce it until a
suitable reading is displayed.
The dial can be rotated 360° through the following zones:
• DC voltage (DCV)
• AC voltage (ACV)
• DC current (DCA)
• Resistance (OHMS)
• Battery voltage (BATT V)
Important: Disconnect the probes from any load before
adjusting the function dial.
6.3 Voltage Measurement
1. Use the function dial (3) to select the appropriate
range from the DC voltage ranges or AC voltage
ranges zone as appropriate.
2. Position the probe contacts across the source of the
circuit to be measured, observing the correct polarity.
3. Enable power to the circuit to be measured and read
the value from the appropriate scale on the gauge.
Important: If the reading is not appropriate for the
circuit, disconnect the probes from the circuit and
adjust the function dial to a more appropriate range.
6.4 DC Current Measurement
1. Use the function dial (3) to select the appropriate
range from the DC current ranges zone.
2. Open the circuit to be measured and connect the
probes in series, using the correct polarity, to bridge
the gap.
3. Enable the power to the circuit to be measured
and read the value from the appropriate scale on
the gauge.
Important: If the reading is not appropriate for the
circuit, disconnect the probes from the circuit and
adjust the function dial to a more appropriate range.
6.5 Resistance Measurement
1. If the resistance to be tested is part of a circuit,
switch the circuit o, disconnect the power and allow
all capacitors to discharge before measurement.
WARNING! NEVER measure resistance
across a voltage source or on a
powered circuit.
2. Use the function dial (3) to select the appropriate
range from the resistance ranges zone.
3. Touch the two probes together to short-circuit the
leads and use the ohms adjustment dial (6) to set
the gauge needle to a zero reading (top-right of
the gauge).
4. Touch the probe contacts at either side of the
resistance to be measured and read the value from
the appropriate scale on the gauge.
Important: If the reading is not appropriate for the
circuit, disconnect the probes from the circuit and
adjust the function dial to a more appropriate range.

EN
6.6 Battery Test Function
Important: This product can be used to test batteries
of up to 9V.
1. Use the function dial (3) to select the battery
test function.
2. Touch the probe contacts against the contacts
of the battery, observing the correct polarity.
3. Read the value from the appropriate scale on
the gauge.
Important: If the reading is not appropriate for the
circuit, disconnect the probes from the circuit and
adjust the function dial to a more appropriate range.
6.7 Manual Zero Adjustment
The needle of the display gauge (2) should rest at the
far left of the scale when the device is not in use. If the
needle does not return to this position, it can be
manually adjusted by using a plain slot screwdriver to
rotate the manual zero adjustment screw (4).
Important: After adjusting the zero screw, test the device
to ensure that it delivers accurate readings and returns to
the zero position as appropriate.
6. Operating Instructions
Important: Disconnect the probes from the terminals
and any other source of voltage before performing any
maintenance on this product.
7.1 Maintenance and Storage
• Keep the product clean and free from dust, debris and
grease.
