Unit: HZ (1-5000)
Note 1: Calculate the corresponding instantaneous
flow rate, current value, and pulse (frequency) value
according to the input sensor frequency value, and
output it.
These values are also read through RS485.
The cumulative flow advances just like the real mode
for validation.
Note 2: The test mode will only be executed after a
new value must be entered, and the LCD backlight
will flash at this time.

Note 1: This function only outputs the specified
frequency value. The instantaneous flow rate value
and current value at this time are not affected. The
cumulative flow remains the same.
Note 2: The test mode will only be executed after a
new value must be entered, and the LCD backlight
will flash at this time.

Unit: mA (3.9-21)
Note 1: This function only outputs the specified
current value. The instantaneous flow rate value and
pulse output value at this time are not affected. The
cumulative flow remains the same.
Note 2: The test mode will only be executed after a
new value must be entered, and the LCD backlight
will flash to indicate in test mode.
