13.3 Adjusting Analog Output
The current of analog output has been adjusted at the time of factory shipment. If, however, any error is present
in the output value and measurement value depending on your service environment, adjustment of the current
of analog output is available.
Analog output adjustment begins from "A.trim" of Setup mode.
■
Preparation for adjustment
Connect the ammeter to the analog current loop in series.
(Using the current monitoring function of the connected measurement, control instrument, etc. are also
permitted.)
Be careful not to cause unexpected operation of external instrument due to variation of current.
■
Adjustment of 4mA output
Enter the adjustment mode from "trm.04" (layer code 13-01) of "A.trim" submenu in the Setup mode.
Perform adjustment for 20mA from the menu "trm.20" in the same manner.
After setting, "Press and hold SEL" from the Menu to return to "A.trim" display. Then simulative output is
cleared and normal output state is restored. (Simulative output continues in the "A.trim" submenu.)
