NOTE:
1. All other controller parameters are company set and locked. It is recommended not
to change them.
2. When the source is operated at any temperature above ambient, the front face and
plate become hot.
3. Always put the fan in “ON” Condition and do not switch the “Mains” off
Directly, First set the controller to 0 Deg C and then wait until the unit is not
cooled below 100 Deg C.
7.3 Operating Instruction:
1. Connect the ‘ CALsys 250 ’ to a suitable power supply.
2. Fill the oil in the bath, up to the marked line, Connect the power Supply to the
heater and stirrer.
3. As soon as the power is ON you shall observe display on the controller.
4. Place the UUC (unit under calibration) & Master sensor into Insert.
5. Set the controller to the required Temperature.
6. If test & master sensor is Thermocouple then always use compensating cable (for
each type like J, K, T, E, N, R, S, B) for interconnection between sensor and
DMM.
7. Keep reference junction at 0 Deg C, if not possible then add mili volt (mV) of
room (ambient) temperature with sensors output mV to compensate the ambient
temperature.
8. When temp of the controller are stable record the reading from DMM with at least
41/2 digit precision which should be calibrated for the measuring range (mV &
ohms measurements).
9. Find out the error by comparison method.
