2 - T-350P / T-650P Calibrators Operation

The T-350P/T-650P calibrators keep the block temperature controlled and allow
the reading of a thermo-element connected to its terminals. It is possible to verify the
thermocouple, thermoresistances, temperature transmitters etc together with the block
temperature value and temperature setpoint.
The calibrators have 3 operating modes:
 Manual Mode to select the block temperature straight from the keypad.
 Programmable Mode: 6 different programs with 11 temperature setpoint values. The
block temperature is selected among the programmed values by the keys
The Programmable Mode with Timer scans automatically the temperature setpoints.
 Automatic Mode to calibrate thermo-elements. The thermo-elements calibration is
performed in an automatic way by the calibrator: the schedule and the calibration
results, besides the thermo-element readings are stored in the calibrator memory.
When powered on (ON/OFF key), the calibrator goes through a self-test routine
and shows the last calibration date and the value of the battery voltage. The battery
voltage is constantly monitored and the low battery warning is provided. After the self-
test is completed, the display shows the starting menu.
The initial setpoint is 25.00 ºC:
By means of keys
