6. Inspection
6.1 Receiving inspection
In case you inspect at the time of receiving, please perform after reference the following.
(1) Structure
Inspection of an outline dimension, mounting dimension, and appearance.：Please perform with reference to
dimensional outline drawing.
(2) Performance
Please do a reserve energization (warm-up) for 15 minutes after a power supply apply. After that, please
conduct performance inspection. Performance inspection is performed with reference to 7.2 "calibration
method".
6.2 Periodic inspection
Please perform the following item if needed.
(1)
Please check each set value.
(2) The accuracy test of indicated value.
An input tests indicated value as two to five points.
(3) Alarm output operation and setting accuracy.
The check with normal ON/OFF operation. The accuracy of operation value and reset value (dead band) is tested.
7. Check, calibration and maintenance
7.1 Check
It is not necessary to check especially every day. Please be periodically careful of the next item.
(1) It is checked whether a body and socket combination are normal (is a lock a totality?).
(2) It checks for the slack of wiring, and the slack of a captive screw.
(3) It will remove, if dust has adhered to the case.
7.2 Calibration
Calibration is performed in the calibration circuit of the right
figure.
(1) Please do a reserve energization (warm-up) for 15 minutes after
a power supply apply.
(2) When the input equivalent to the minimum display is applied,
in order that it may become the minimum display, set value
CBIAS is set up.
Next, when the input equivalent to the maximum display is applied,
in order that it may become the maximum display, it sets up
by set value CSPAN.
Calibration is finishing, if the above is checked again and
the display is correct. In addition, please refer to the
4.5 section "set value change mode" about setting of set
value CBIAS and CSPAN.
(3) Please perform the check of an operation value, a reset
value, and a dead band.
