13.4 Loop Check
In each display mode, regardless of applied pressure, the loop
check can be activated by following the push button sequence in
Section 13.1 and 13.2. This will link the display with the analog
output. This allows for checking wiring, receivers, general trou-
bleshooting etc.
• Loop check method (Linear Display Mode)
1. Turn and remove the lid of this product.
2. Shift to the linear display mode in the setting item
ባ. (Refer
to Section 13.2, Setting Procedure). The display at the time
of loop check start (zero point) and the analog output (4mA)
are held.
3. If $ button continues to be pressed, the linear display will
auto-increment by linkage between the linear display and the
analog output. By continuing to press # button, auto decre-
ment will occur. Release the button at the desired indication.
For example, if the button is released at 2.50(ton), the dis-
play will stop and be held at analog output 12mA correspon-
ding to the indication.
