Description
Orbit Controls Model OC 502-t is a Calibrator-Multimeter which generates currents 0/4-22mA in Source or Sink mode and Voltages 0 to 14V. External voltages ± 2V, ± 20V and ± 200VDC (firm ranges or Auto ranging) and currents up to ±100mA can be measured while the calibrator generates the selected output signal. Due to this simultaneous operation a response from e.g. external transmitters under test can be measured with the calibrated signal from OC502-t. Both the generated calibration signal and the measured external signal are displayed. For calibration of mV devices such as strain gauges chains, Millivolt outputs 0-28mV or 0-560mV with high resolution are available.
DIN Thermocouples J, K, N, R, S, T, B, E can be simulated in positive temperature range. The sensor type will be selected and the required temperature entered with the keyboard. The display shows the temperature, the mV output is at the output terminals. The junction is compensated for the ambient temperature with internal sensor. The compensation can be switched-off.
OC502-t can be software recalibrated via the keyboard whenever required. The instrument is supplied from internal rechargeable battery which permits 9 hour uninterrupted operation.
Background light can be switched on.
