3.10 Temperature Sensor Setup
From the Main menu, select the Temperature Sensor Setup menu and press
Enter
or the ad-
justment knob.
Select Temperature Sensor by pressing
Modify
or the adjustment knob.
The Temperature Sensor line is in entry mode, the border is flashing. By pressing
Previous
or
Next
or by turning the adjustment knob you can choose the appropriate temperature sensor:
AD590:
current sensor, means also AD592, 1 µA/K
Thermistor (low): NTC Thermistors, measurement range 100
W
to 100 k
W
Thermistor (high):
NTC Thermistors, measurement range 1 K
W
to 1 M
W
PT100:
Platinum RTD sensor, 100
W
at 0°C
PT1000:
Platinum RTD sensor, 1000
W
at 0°C
LM35:
Voltage sensor, 10 mV/°C, 0 V at 0 °C
LM335:
Voltage sensor, 10 mV/K, 0V at 0 K, means also LM235 / LM135
Confirm your choice with
Done
or by pressing the adjustment knob again.
For IC sensors, the calculation coefficients are predetermined by your ITC4000: 1µA/K for the
current sensors AD59x, 10mV/°C for LM35 and 10mV/K for LMx35.
If no temperature sensor is connected or if the temperature sensor does not correspond to the
selected sensor type, the red LED in the “TEC ON” key (F6, see
) lights up and in the the status line the indicator "SENSOR" is shown. If the TEC
output is switched on and the sensor lines are broken the TEC output will be switched off im-
mediately. An short beep and an error message “Temperature sensor failure detected” appears
at the bottom of the measurement display.
