Safety Information
3
• Never use the Calibrator with the red holster
removed.
• Never use the Calibrator with the case open.
Opening the case violates Ex Approval
• Make sure the battery door is closed before you
use the Calibrator.
• Replace the battery as soon as the M (low
battery) symbol appears to avoid false readings
that can lead to electric shock.
• Remove test leads from the Calibrator before
opening the battery door.
• This equipment is specified for use in
measurement category I (CAT I) pollution
degree 2 environments and should not be used
in CAT II, CAT III, or CAT IV environments.
Voltage transients should not exceed 300 volts
for the CAT I applications where this product is
used. Measurement transients are defined in
IEC1010-1 as 2 µs rise time with a 50 µs
duration at 50 % of the maximum amplitude
height.
• Measurement Category I (CAT I) is defined for
measurements performed on circuits not
directly connected to the mains.
Safety Advice
To ensure safe operation of the Calibrator fully observe all
instructions and warnings contained in this manual. In
case of doubt (due to translation and/or printing errors)
refer to the original English manual.
Faults and Damage
Applying a voltage greater than 28 V to the input of the
Calibrator invalidates its Ex Approval and may impair its
safe operation in an Ex-hazardous area.
If there is any reason to suspect that the safe operation of
the Calibrator has been affected, it must be immediately
withdrawn from use, and precautionary measures must be
taken to prevent any further use of the Calibrator in an Ex-
hazardous area.
The safety features and integrity of the unit may be
compromised by any of the following:
• External damage to the housing
• Internal damage to the Calibrator
• Exposure to excessive loads
• Incorrect storage of the unit
• Damage sustained in transit
• Correct certification is illegible
• Using the product with the red holster removed
• Functioning errors occur
• Permitted limitations are exceeded
• Functioning errors or obvious measurement
inaccuracies occur which prevent further measurement
by the Calibrator
