√Software calibration
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
Autoranging) 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.
Back ground light can be switched on.

Orbit Controls Model OC 502-V2-100 is a Calibrator-Multimeter for
generation of 0/4 - 110mA in Source and Sink mode and Voltages
between 0 to 11V. External voltages ± 2V, ± 20V and ± 200VDC (firm
ranges or Autoranging) 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. an external transmitter
under test can be measured which is signal supplied from OC502-V2-
100. Both, the generated calibration signal and the measured external
signal are shown at the LCD digital display
OC502-V2-100 can be software calibrated via the keyboard whenever
required.
The instrument is supplied from internal battery and permits an uninterrupted operation of 3-4 hours with
the output current between 0 and 20mA. For higher output currents up to 100mA the calibrator has to be
connected to the charger. When the display shows BAT of the battery capacity, the calibrator has to be
connected to the charger.
