Safety Information
This manual contains information that must be
followed for operating the meter safely and
maintaining the meter in a safe operating condition.
If this meter is not used in the manner specied, the
protection provided may be impaired.
Warning! Warns of potential danger, refer to the
instruction manual to avoid personal injury or
damage to the meter.
Caution! Dangerous voltage. Danger of electrical
shock.
Continuous double or reinforced insulation
complies with IEC536, class II.
Symbol of conformity, conrms conformity with
relevant EU directives. The meter complies with
EMC directives (89/336/EEC). Specically stand-
ards EN 50081-1 and EN 50082-1 as well as the
Low Voltage Directive (73/23/EEC) described in
the standard EN 61010-1.

Safety Information Safety Information
The meter has been designed in accordance with
the safety regulations for electronic measuring
instruments, EN 61010-1, IEC 61010.
Voltages above 75V DC or 50V AC may constitute a
serious shock hazard.
Before using the meter check for physical damage to
the casing in particular around the connectors. If the
case is damaged do not use the meter.
Check the test leads for damaged insulation or
exposed metal. Check the leads for continuity.
Replace damaged leads with identical model or
specication before using the meter.
Where applicable use GS38 approved leads (not
supplied) these are available from Di-Log. When using
test leads keep ngers behind the nger guards.
Do not apply more than the rated voltage, as marked
on the meter between the terminals or between any
terminal and ground.

Safety Information
Before making a measurement ensure that the rotary
switch is set to the appropriate range. Do not turn the
rotary switch whilst making a measurement.
Use the appropriate terminals, function and range for
your measurements. If the value to be measured is
not known use the maximum measurement position
and reduce the range step by step until a satisfactory
reading is obtained.
Do not use or store the meter in an environment of
high temperature, humidity, fumes, vapour, gaseous,
inammable and strong magnetic eld. The perform-
ance and safety of the user may be compromised in
such circumstances.
Disconnect circuit power and discharge all high
voltage capacitors before testing resistance,
continuity, diodes, capacitance or current.
Before measuring current check the meters fuses and
turn off power to the circuit before connecting the
meter to the circuit.

Safety Information Safety Information
Replace the battery as soon as the low battery
indicator appears. If the battery is low the meter
may give false readings.
Turn the meter power off when not in use,. Remove
the battery if the meter is in use for a long period.
Constantly check the battery as it may have leaked.
A leaking battery will damage the meter.
The meter may only be opened by a qualied service
technician for calibration and repair.

Specication
Warning:
RISK OF ELECTROCUTION. HIGH-VOLTAGE CIRCUITS,
BOTH AC AND DC, ARE VERY DANGEROUS AND
SHOULD BE MEASURED WITH GREAT CARE.
1. ALWAYS turn the function switch to the OFF
position when the meter is not in use. This meter
has Auto OFF that automatically shuts the meter
OFF if 15 minutes elapse between uses.
2. If “OL” appears in the display during a measure-
ment, the value exceeds the range you have
selected. Change to a higher range.
Note:
On some low AC and DC voltage ranges, with the
test leads not connected to a device, the display
may show a random, changing reading. This is
normal and is caused by the high-input sensitivity.
The reading will stabilize and give a proper
measurement when connected to a circuit.
