MICROHMMETER
OM 16:
On-site microhmmeter
OM16 milliohmmeter / microhmmeter is firstly a
designed for outdoor uses instrument but also in
workshop , and maintenance departments.
Easy to use, it performs measurements on
inductive and non-inductive resistances with a DC
current.
Its large interactive display informs in real time the
operator about the type of measurement, range,
calculation conditions (resistance calculated
according to a reference temperature), thresholds
status and values.
Designed for hard conditions:.
- Hard case (Pélicase type).
- Plastic washable keyboard.
- Key-locked measurement plugs.
Resistance is automatically calculated by the
instrument taking into account: measurement
value, ambient temperature, metal
temperature coefficient, reference
temperature
All parameters are programmable. (Ambient
temperature can be programmed or measured
thanks to the temperature sensor)
Why choosing an OM 16
•
4 wires measurement to provide highest
accuracy
•
Automatic measurement in non inductive
resistance mode. :automatic triggering when
continuity is established between the two
points :a single operator can perform
measurements.
•
EMF parasites are measured before each
measurement
•
Permanent measurement current for inductive
loads (coils, transformers, motors windings).
•
DC measurement current for non-inductive
resistances (earth bonding, coating, contact
resistances) with auto power off of the current.
•
•
2 programmable thresholds with LED indication
and display on the screen, light or loud beeper.
•
Memory: 1 000 measurements identified by
numbers.
Memory reading on the display, or via software
or printer.
•
Powered by NiMh batteries, quick charge
Display of temperature compensated resistance
