SET-UP PROCEDURE
Configuring the Engineering Units
In order to configure the engineering units (GPM or LPM), proceed as follows:
1. Press and hold the MENU pushbutton, the display shows “---”. Continue holding the pushbutton for at
least 5 seconds.
2. The display shows either “G” (for GPM) or “L” (for LPM), depending on what engineering unit was
previously set.
3. Release the ALARM SET pushbutton.
4. Use the ALARM SET pushbutton (press and release) to toggle between “G” and “L”, then do not
touch the pushbutton until the flowmeter returns to normal operation.
Note: It may take up to 20 seconds before the meter returns to normal operation.
Do not touch the pushbutton unless you want to change the alarm setting, as described below.
Configuring the Flow Alarm
In order to configure the flowmeter for alarm output, proceed as follows:
1. Press and hold the ALARM SET pushbutton, the display shows “---”. Continue holding the
pushbutton for at least 5 seconds.
2. The display shows either “G” or “L” depending on which engineering unit has been selected.
3. Wait 5 seconds. During the 5-second period, you can either continue holding the ALARM SET
pushbutton, or release it. If you release the pushbutton, do not push it again. (If you press and
release the pushbutton at this point, the display toggles between “G” and “L”, assuming that you
are changing the engineering units.)
4. The 3-digit value that starts blinking on the display is the alarm setpoint (as stored in the
memory). If you do not press ALARM SET, the display continues to blink for 10 seconds, then the
meter reverts back to normal operation.
5. Use the ALARM SET pushbutton to change the alarm setpoint, if needed.
Note: When ALARM SET is pressed once, the display stops blinking and increments to the next value.
ALARM SET can either be held down continuously, or pressed and released repeatedly. When the
maximum setpoint value is reached, the display rolls over to the minimum value again. Setpoint values
are pre-programmed. Please refer to Table 1 (below) for more details.
6. When the desired alarm setpoint is displayed, do not touch the pushbutton for 10 seconds. The
displayed value is saved in the memory and the meter returns to normal operation.
