SAFETY A
NTA47262-000A6 7 / 55
A.3 Main Characteristics
• Programming and operating the unit using a 14-key keypad: selection of range, measurement mode
(low inductive or inductive resistance), temperature compensation and measurement triggering.
• Measurement memory function.
• Programmable alarms that are triggered when thresholds are exceeded.
• Portable unit with battery pack comprising five Ni-MH accumulators, 8.5 Ah (D cell size).
Battery pack recharge: A charger built into the OM 17 recharges the batteries by connecting the unit to the line
(90 V/264 V, 45 Hz/420 Hz), using a standard cord.
Recharge time: 5 hours.
Endurance: 5,000 measurements using a 10 A current level in low inductive mode.
• 4-wire measurement with automatic compensation of spurious voltages.
• Automatic compensation of ambient temperature by measuring it using an external sensor or by
manual entry and programming of the metal type or its temperature coefficient.
• LCD display.
• Direct display of the measurement together with its unit, range, measurement mode and if required,
temperature compensation.
Measurement can be triggered from the keypad, remotely, or in automatic mode.
• Sealed, sturdy casing.
• Dimensions: 270 mm x 250 mm x 180 mm.
• Weight: approximately 4 kg
A.4 Safety Provisions
Compliance with Safety StandardsA.4.1
The unit has been constructed and tested in accordance with safety rules relating to electronic measuring
instruments.
This instruction manual contains information and cautionary advice that users must follow to: protect
themselves against electrical shocks, ensure the reliability of the unit, and make sure that the unit is not used
in a way that could damage it or make it unsafe for use.
Following Instructions supplied with the accompanying DocumentsA.4.2
The unit is constructed to operate in complete safety as long as the instructions supplied with the
accompanying documents are followed. Any usage, except those described, may impair operator safety and is
therefore dangerous and prohibited..
Taking MeasurementsA.4.3
The test leads and measuring wires must be in good condition and should be changed if there is any evidence
of deterioration (insulation split, burnt, etc.).
Never exceed the safety values indicated in the specifications.
Never connect the unit to a live circuit.
When the unit is measuring resistance showing a high inductive component (transformers, motors, etc.) after
ending the measurement (with the measurement current cut-off), the unit then discharges this inductance
and displays the icon for this entire duration.
Never disconnect the connection wires before this icon disappears.
Instructions to be followed before UseA.4.4
a) Charging batteries
During battery charge, instrument must be placed on a flat surface with cover opened, in order to connect
instrument to the main power supply. (The cable plug and the main are creating a disconnecting device ) .
During battery charge, any other cable must be disconnected and removed from the instrument
Power cable must remain the one supplied with the instrument (H03VVH2-F2).
