8.2.12 Display low cut On/Off

When the low output is cutoff by the setting in 8.2.10 “Low cutoff value,” whether the instantaneous
flow rate, flow velocity and % value should be set to zero or not can be selected.

Selection

Display low cutoff

1: ON

Display low cut is effective (On)

Display (instantaneous flow rate, flow velocity and %) will be set to
zero when the low output is cutoff.

2: OFF

Display low cut is not effective (Off)

Measured value will be output even if the low output is cutoff.

Checking whether the display low cut is On or Off

Proceed as follows to check whether the display low cut is On or Off.
