Safety Notices
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 specifi 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 11
Symbol of conformity, confi rms conformity with
relevant EU directives. The meter complies
with EMC directives (89/336/EEC). Specifi cally
standards EN 50081-1 and EN 50082-1 as well as
the Low Voltage Directive (73/23/EEC) described
in the standard EN 61010-1.
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.
Safety Notices
Check the test leads for damaged insulation or
exposed metal. Check the leads for continuity.
Replace damaged leads with identical model or
specifi cation before using the meter.
Where applicable use GS38 approved leads (not
supplied) these are available from Di-Log. When using
test leads keep fi ngers behind the fi nger guards.
Do not apply more than the rated voltage, as marked
on the meter between the terminals or between any
terminal and ground.
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, infl ammable and strong magnetic fi eld.
The performance and safety of the use may be
compromised in such circumstances.
Disconnect circuit power and discharge all high
voltage capacitors before testing resistance,
continuity, diodes, capacitance or current.
Safety Notices
Before measuring current check the meters fuses
and turn off power to the circuit before connecting
the meter to the circuit.
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 qualifi ed service
technician for calibration and repair.
