Instruction of Installation
1. The product has adopted structure compliance with EN50022; suitable for DIN rail mounting
NS35/7.5, NS35/15. Installation steps are as following (please reference to dimensional drawing):
Step 1: Immobilize one side of product‘s mounting trough to the DIN mounting rail;
Step 2: Pull out the spring clasp;
Step 3: Place whole mounting trough to the DIN mounting rail properly;
Step 4: Release spring clasp to make sure the installation.
2. The product has calibrated before out of factory. After correctly wiring, it can be powered and
used immediately. But for further precise signal sampling, user need to warm-up the product for 3
minutes before use.
3. output signal (Iz) is designed to follow the impedance load value of 250
Ω
;
When Resistance
(R
1
) is less than
100
Ω
,
the user must add output current circuit a power reduced resistance load R
0
to keep the summation of total impedance value is between
100
Ω～
250
Ω
4. basic testing method for accuracy
(1) According to the terminal definition table to connect the testing circuit;
