2. PRODUCT SPECIFIC SAFETY INFORMATION
Safety: Complies with BS EN 61010 and BS EN 61557.
Overvoltage Category: CAT III 600V, Pollution Degree 2.
This tester has been designed with your safety in mind, however,
no design can completely protect against incorrect use.
Do not touch exposed wiring, connections or other live parts of
an electrical circuit.
When using this tester to monitor high voltages, turn off the
power before connecting the tester.
If in doubt check the circuit first before touching it.
Do not use cracked or broken test leads.
Do not use in wet conditions.
Note: Capacitance Discharge
On completion of an insulation test, the tester should remain
connected to the circuit under test for a short period after releasing
the TEST button. The TEST button if latched must be released.
This discharges any capacitance via the tester. Before
disconnecting the tester ensure indicated voltage is zero.
Warning
Before use check the unit for cracks or any other damage. Make
sure the unit is free from dust, grease and moisture. Also check any
associated leads and accessories for damage. Do not use if
damaged.

WARNING
THIS TESTER SHOULD ONLY BE USED BY A COMPETENT AND
SUITABLY TRAINED PERSON.
REMEMBER - SAFETY IS NO ACCIDENT!
3. OPERATION
3.1 Installing or Replacing Batteries
1. Disconnect the test leads from any live source, turn the rotary
switch to OFF and remove the test leads from the input terminals.
2. Remove the battery cover using a Phillips screwdriver.
3. Install six LR6s (alkaline) batteries.
4. Replace the battery cover.
3.2 REPLACING FUSES
The condition of the fuse can be checked as follows:
Unplug the test leads.
Select continuity (KΩ, or 

))), or 40Ω), press the TEST button. If
the fuse is defective the display will read FUSE Err. The fuse is
located in the battery compartment and is used to protect the
tester if the leads are connected to a live circuit when the
continuity/resistance ranges are selected.
Switch the tester off and release the TEST button. Remove the
battery cover using a Phillips screwdriver and carefully remove the
failed fuse from the metal clips, fit the correct replacement and
re-fit cover.
DO NOT OPERATE THE TESTER WITH THE BATTERY COVER
REMOVED.

WARNING
When the meter shows the " " sign the batteries must be replaced to
maintain correct operation. Follow the procedure below.
3.3 How it Works
VOLTAGE MEASUREMENTS
Ensure the TEST button is released.
Insert the red test lead in VΩ, and the black lead in COM. Connect
the red and black leads across the circuit to be measured - the
measured voltage will be displayed.
When a voltage higher than 30V is detected, the buzzer sounds
and the high voltage indicator ( ) will blink in the upper-right
corner of the display.
ZERO KEY
When measuring low resistances, using the 

))) and 40Ωranges,
compensation for the resistance of the test leads is needed:
Set rotary switch to desired low resistance range, short test leads
by holding them together or, if using croc clips, clipping them
together. Press and hold / latch the TEST button, the resistance of
the leads will be displayed, then press the ZERO soft key to carry
out the compensation; a triangle is shown in the middle of the
display. Press the ZERO soft key again to remove the
compensation.
CONTINUITY MEASUREMENT
Ensure circuit is not live by taking a voltage measurement
Set rotary switch to 40Ωrange. Insert red test lead in VΩ, and
black lead in COM. Connect the red and black leads to the circuit
to be measured and press the TEST button. The measured
resistance will be displayed. If OL is displayed this indicates the
resistance being measured is greater than the continuity range of
5

the tester.
RESISTANCE MEASUREMENT WITH BUZZER
Ensure circuit is not live by taking a voltage measurement
Set rotary switch to

))) range. Insert red test lead in VΩand
black lead in COM. Connect the red and black leads to the circuit
to be measured and press the TEST button. The measured
resistance will be displayed, and if the resistance is below 30Ω, the
buzzer will sound. If OL is displayed this indicates the resistance
being measured is greater than the resistance range of the tester.
The buzzer can be toggled off and on by pressing the ))) key.
RESISTANCE MEASUREMENT
Ensure circuit is not live by taking a voltage measurement
Set rotary switch to KΩrange. Insert red test lead in VΩ, and black
lead in COM.Connect the red and black leads to the circuit to be
measured and press the TEST button. The measured resistance
will be displayed. If OL is displayed this means the resistance
being measured is greater than the resistance range of the tester.
INSULATION RESISTANCE MEASUREMENT (MΩ)
For safety reasons, please adhere to the following procedure for
Insulation Resistance Measurement: Ensure that the TEST button
is unlatched and is released. Turn the rotary switch to select the
voltage to be applied - 500V DC (IN2101) or 250V, 500V or 1000V
DC (IN2102). Insert red test lead in VΩ, and black lead in COM.
Connect the black and red test leads to the circuit to be measured.
Note: If a voltage higher than 30V is present on the circuit under
test, the buzzer sounds and the high voltage indicator ( ) blinks
in the upper-right corner of the display. In this event, remove the
test leads from the circuit under test and proceed with caution to
investigate the source of the voltage on the circuit under test.
6
Press the TEST button to apply the test voltage. This button can
be turned clockwise while pressed to latch it. Allow several
seconds for the reading to stabilise. The test voltage is shown in
the lower-right corner of the display.
Note: On completion of an insulation test the TEST button, if
latched, has to be manually released to discharge the circuit under
test. In the interest of safety the user should be aware of this.
If OL is displayed this means that the resistance being measured
is greater than the measuring range of the tester.
When a low resistance is measured, the test voltage drops; if it
drops to lower than 80V, a blinking indication of 0000 is displayed.
The buzzer can be toggled off and on by pressing the ))) key.
BATT CHECK
Set rotary switch to BATT CHECK range. Press the TEST button,
the display shows the battery voltage as a % and as a voltage.
When the battery voltage is lower than 6.6V, the symbol " "
appears and the batteries should be replaced (see 3.1 page 4).
A-H (Auto-Hold) key
Press the A-H key to enable or disable the auto-hold function
whilst performing a test. When enabled, AUTO HOLD is shown in
the middle of the display with HOLD blinking. With auto-hold
enabled the HOLD stops blinking and the buzzer sounds when a
stable measurement occurs. After the TEST button is released the
measured value is displayed and HOLD resumes blinking. Press
the A-H key to delete the value held on the display.
7
APO (Auto Power Off)
Press and hold the ))) key for >2 seconds to enable/disable the
Auto Power Off function. The APO will turn the tester off after 5
mintues.
Back Light key
Press this key to turn the back light on or off.
