- Page 12 SERVICE MENU - HtESt The Service Menu HtESt permits fast check of the instrument’s performance and offers the software calibration via the keyboard. To enter the Service menu, keep the key MENU pressed while the instrument is switched-on. Release the key when the display shows HtESt. The service menu steps are incremented forward with the key MENU, decremented backward with SET.
- Page 13 CALIBRATION Calibration of linear signals DC and AC The calibration steps are described in §6, Service Menu and HtESt. Linear signals such as 4-20mA, 0- 1V can be calibrated as described. Calibration of non-linear signals (Tables) Input signals such as RTD Thermometer and Thermocouples will be linearized as follows: 7.2.1 Calibration of Pt-100 Thermometer SEnS LinEAr...
