Verification mode
Verification mode increases measurement frequency to provide maximum measurements per
second. All other parameters stay the same. This function is especially useful to minimize
calibration time when validating water meter accuracy. Frame around digits will blink slowly to
indicate that verification mode is enabled. Maximum pulse rate on output A is increased to 1
kHz and pulse width is set to 0.5 ms. When verification mode is exited the previous pulse setting
is restored. Pulse widths other than 1 ms can be selected by storing new pulse values. This
setting remains when verification mode is exited.
Activation of verification mode
Verification mode is enabled in one of the following ways:
● Pressing verification button through hole in front screen.
● Writing integer ‘1’ to parameter 320.
Verification mode
The following indicate that meter is in verification mode:
● Frame surrounding digits in LCD starts flashing.
● Excitation frequency is set to maximum allowable frequency.
– (ExcitationFreqNo = ExcitationFreqNoLimit)
● Resolution in display is set to 3 digits after decimal point.
– (DecimalPoint = 3)
