Thermocouple Digital Indicator DAT735 LCD or LED
GENERAL DESCRIPTION
The DATEXEL DAT735 is a 3.5 digit LCD or LED digital indicator with high accuracy and reliability able to measure Temperature from a Thermocouple probe.
The DATEXEL DAT735 is designed for mounting in a panel in accordance with DIN 43700 standards .
The zero and span can be adjusted with potentiometers located on the rear of the DATEXEL DAT735.
The DATEXEL DAT735 is designed for mounting in a panel in accordance with DIN 43700 standards. It also has a function to freeze (HOLD) the display.
The DATEXEL DAT735 is in compliance with the directive CEE/336/89 on the Electromagnetic Compatibility.
USER INSTRUCTIONS
The digital thermometer DATEXEL DAT735 must be connected as follows.
Connect the power supply between the terminals T3 (+V) and T2 (GND); in order to avoid damages for the device, the power supply value
must be lower than 5.5 Vdc.
The input sensor must be connected between the terminals T4 (+Tc) and T5 (-Tc).
The complementary function HOLD could be used to freeze the measure at the last value detected. To use this function connect the terminal
T1 (HOLD) to the terminal T2 (GND); in order to avoid damages for the device, it is recommended to active this function for a maximum time
of 2 minutes.
To calibrate and install the device refer to sections “Calibration DATEXEL DAT735” and “Installation Instructions”.
