8.6 Verification

For setting up date and time, the different key function must be used - see Operator menu
(Page 62). An "A" indicates an acceptable value and a flashing "A" indicates that value is stored
when key is released.
Reset function also sets actual date as battery replacement date.
8.6 Verification
Verification mode increases measurement frequency to provide maximum measurements per
second. This function is especially useful to minimize calibration rig 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 or
● Writing integer '1' to parameter 320 (Calibration mode).
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)
