Simulation Of Temperature Sensors - Metrix CX 1651 Manuel De L'utilisateur

Calibrateur multifonctions CX 1651
Setting the duty cycle
Duty cycle can only be set in PWM mode.
•
Select the frequency mode and keep pressing the center cursor button until [ _ _ _ _ _ _ _ ] symbols appear
under the duty cycle value (PWM = xx %).
•
Set the value using numeric keyboard, cursor buttons or potentiometer and confirm by pressing % display
button or by pressing ENTER.
Setting the signal shape
Signal shape can only be set in PWM mode.
•
Keep pressing SHAPE display button to select desired signal shape NEG – negative, SYM – symmetrical,
POS – positive.
•
Output signal of desired shape is connected to the output connector.

Simulation of temperature sensors

The multifunction calibrator can simulate resistance temperature sensors and thermocouples. When resistance
temperature sensors are simulated, a simulated resistance corresponding to set temperature, sensor type and
temperature scale is connected to Hi - Lo terminals. When thermocouples are simulated, a simulated voltage
corresponding to set temperature, sensor type and temperature of cold end of thermocouple is connected to Hi -
Lo terminals.
Simulated values of temperature sensors are also available at the AUXILIARY connector. Thermocouple voltage
is available at +U, -U terminals. Four-wire connection of resistance temperature sensors is provided by current
terminals PTLI, PTHI and voltage terminals PTLU, PTHU. 140-41 cable adapter is recommended.

Switching between resistance temperature sensors and thermocouples
•
Press T button on the calibrator. The main value on the display is set temperature. The calibrator simulates a
resistance temperature sensor.
•
Press T button on the calibrator once again. The calibrator simulates a thermocouple.
Setting the temperature
•
Press T button on the calibrator. The main value on the display is set temperature.
