18.14.6. 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.
18.15. 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.
Temperature setting range: -250 to +1820
o
C depending on simulated sensor type
Sensor types: resistance temperature sensor Pt 1.385, Pt 1.392, Ni
thermocouple K, N, R, S, B, J, T, E
Temperature scale: ITS 90, PTS 68 for resistance temperature sensors and thermocouples
18.15.1. 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.
18.15.2. Setting the temperature
• Press T button on the calibrator. The main value on the display is set temperature.
• The display shows the following data:
* main data of temperature in
o
C or K
* sensor type thermocouples: K, N, R, S, B, J, T, E
resistance temperature sensors: Pt 1.385, Pt 1.392, Ni
* resistance at 0
o
C labeled R0 (resistance temperature sensors only)
* cold junction temperature of thermocouple sensors labeled RJ
* set value of relate deviation in %, labeled ∆T = xxxx.x °C (K)
the information section shows:
* temperature scale type
* uncertainty of simulated temperature value of selected temperature sensor type
• Set the main value of temperature using numeric keyboard, cursor buttons or potentiometer. Output
terminals are disconnected, the information section of the display shows the symbol which shows
that output terminals are disconnected.
• Connect the object to be calibrated to Hi - Lo terminals.
• Press OUTPUT button.
