7. Setup
Setup should be done before using this instrument according to the user’s conditions:
Setting the ORP input function (Input indication high limit, Input indication low limit),
EVT1, EVT2, EVT3 (EVT3 option) and EVT4 (EVT3 option) types, Communication (C5option), Transmission output, Indication settings (Backlight selection, ORP color, etc.),
Cleansing action, etc.
Setup can be conducted in the ORP Input Group, EVT1, EVT2, EVT3, EVT4 Action
Groups and Basic Function Group.
If user’s specification is the same as the factory default of the AER-101-ORP, or if setup
has already been completed, it is not necessary to set up the instrument. Proceed to
Section “8. Calibration (p.37)”.
7.1 Turn the Power Supply to the AER-101-ORP ON.
For approx. 4 seconds after the power is switched ON, the following characters areindicated on the ORP Display and Setting Display.

During this time, all outputs are in OFF status, and action indicators turn off.
After that, measurement starts, indicating the item selected in [Backlight selection(p.33)], [ORP color (p.34)], [Bar graph indication (p.35)] and [Setting Display indication(p.35)] in the Basic Function Group.
This status is called ORP Display Mode or Cleansing Output Mode.

ORP input filter time constant
0.0 seconds• Sets ORP input filter time constant.
Even when ORP value before filter process changes as shown in(Fig. 7.2-1), if the filter time constant “T” is set, the ORP valuechanges as shown in (Fig. 7.2-2) so that ORP value after finishingfilter process can reach 63% (of the desired ORP value) after T
seconds have passed.
If the filter time constant is set too large, it affects EVT action due
to the delay of response.
(e.g.) If the LSD (least significant digit) of the ORP value prior tofilter process is fluctuating, it can be suppressed by using thefilter time constant.
