Cầu đo điện trở 1 chiều OM 22
Programmes
OM22 is delivered with 6 pre-set programmes directly accessible by 6 pushbuttons. These programmes are established according to user needs and are loaded into the instrument from a PC via RS232. Each programme defines the range, current (type and value), number of measurements per cycle and timing, storage (or not) of values, temperature compensation if needed, calculations of heat-up in degrees, or calculation of line resistance in W/km, alarm values, maximum measurement voltage, analogue output.
The OM22 can be delivered programmed by AOIP to the user’s specification. These
programmes can also be loaded or modified by the user with a PC, and this task is
facilitated by the programming software developed by AOIP.
Display
26 000 counts, 16-segment illuminated
LCD, 11.5 mm high, alphanumeric characters for messages, measurement indication includes value and unit of measurement.
Incorrect connections or measurements going beyond range are indicated by an error message.
Four-wire measurement
Measurement time
< 1 second in continuous mode,
< 2 seconds in pulsed mode,
< 3 seconds in alternating pulsed mode.
Protection
• Electronic protection against break-off currents when measuring an inductive resistance,
• Possibility of limiting the voltage across the resistor terminals to 20 or 50 mV.
Environment
Nominal operating range: 0 to 50°C, 20 to 75% relative humidity.
Operating range limits: -10 to 55°C, 10 to 80% relative humidity.
Power supply
● 110/220 VAC ± 10%, 50/60 Hz,
● optional battery with built-in charger.
Presentation
Bench unit with optional rack mounting kit.
Dimensions: 225 x 88 x 310 mm.
Weight: 2 to 3 kg depending on options.

All the functions and characteristics to be measured are set up by programme. For each application, the most appro priate parameters of measurement can be defined and then programmed, so that they are available for subsequent instant recall
