Menu Functions A - H:

A. Selects display contrast: 4 levels B. Sets flow units (gpm) and timebase (gpm). Flow units label: Aa - Zz, 0 - 9;

Timebase options: s=seconds, m=minutes, h=hours, d=days (timebase

effects flow display and 4 to 20 mA output) C. Sets flow K-factor: 000.01 to 99999. (see technical notes below) D. Set totalizer units: For label purposes only E. Sets totalizer K-factor: 000.01 to 99999. (see technical notes below) F. Sets 4 mA setpoint (4 mA and 20 mA setpoints are reversible) G. Sets 20 mA setpoint H. Sets user defined date

Technical notes:

Flow and totalizer K-factors are independent of each other. These K-factors represent the number of pulses generated by the flow sensor for each engineering unit measured (published in flow sensor manual).

9. Accessories

A. Selects totalizer reset options: Lock on (enables) or lock off (disables) the

VIEW menu totalizer reset security code feature (RST: -- -- -- --).

B. Selects display averaging: off = 100ms, low= τ=700ms, hi= τ=3s (also

affects 4 to 20 mA output). C. Selects display decimal: D. Adjusts 4 mA output: 3.9 to 4.1 mA (overrides 4.00 mA factory calibration) E. Adjusts 20 mA output: 19.8 to 21.0 mA (overrides 20.00 mA factory

calibration)

11. Troubleshooting

Display Message Cause Solution

1) Input frequency too high

2) Display overrange

3) Display timebase too large

K-Factor cannot be zero

2s

Memory corrupted

2s

(side view)

1) Reduce input frequency.

2) Move display decimal to right in OPTIONS menu.

3) Change display timebase (H,M,S,D) to smaller value (e.g. LPH to LPM).

Change K-Factor to a non-zero value.

Press to restore normal operation. Settings will revert to factory default. Recalibration is required.
