3-10 Electrical and IDOS operations K0449 - [EN] English
1. Set the applicable software options; see Section 3.2.1
(Procedure overview) . This example shows one function:
•
Thermocouple (TC) is set to source a temperature. The
Utility is set to Switch Test . The Automation is set to Ramp;
see Section 2.11.2 .
2. Complete the electrical connections. Because it is a
Channel 1 function (TC), you must have the switch
connections on Channel 2 (CH2).
3. For the Ramp process, set “High” and “Low” values that are
applicable to the switch value. Then, to get an accurate
switch value, set a long “Travel” period.
Use Start/Stop to start and stop the “Ramp” cycle. If
necessary, supply the output values in the opposite direction
until the switch changes condition again.
4. The display shows:
•
the values to open and close the switch
•
the hysteresis value
5. To do the test again, use the reset button.
3.3 Measure
pressure: IDOS option
Optional item. An IDOS Universal Pressure Module (UPM)
uses Intelligent Digital Output Sensor (IDOS) technology to
measure the applied pressure and supply the data to an IDOS
instrument.
Before you use an IDOS module, read the user manual: K0378,
Druck IDOS UPM.
Note: To attach an IDOS module to the DPI 620 calibrator, you
must have an adaptor: IO620-IDOS-USB.
