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.

2 OUTPUTS and INPUTS

CALIBRATOR: Voltage and Current Output: + OUT -
MULTIMETER: Voltage Input: GND, IN-V
Current Input: GND, IN-I

3 LCD DISPLAY

The LCD Display is divided into 2 sections. The upper part shows the multimeter functions, the lower
part shows the generated calibrator signals. A Bargraph in the middle displays the measured values as
an analogue function. The left side of the display shows various statements:

AUTO-FIX Automatic Range selection or Firm Ranges
200V Firm Ranges 2V, 20V, 200V, 100mA
INP The display shows the input signal. With FN the following functions can be set:

HLD Display HOLD
MAX Maximum Value Hold
MIN Minimum Value Hold

RST Reset the max. and the min. values to zero
NUM Direct value selection with the keyboard
RMP Automatic Ramp
SUP Charger plugged, Battery is charged
99% Battery voltage shown in % of full capacity. Charge the battery when less

than 0% is displayed. Charge only with the enclosed original charger.

ATTENTION!

In the Current Sink Mode the switches SNK-I and OUT-I have to be selected. Do not switch to OUT-V!

The Current and the Voltage Outputs might be destroyed!
