Operation
F3 – Flow Rate Alarm Enable
If enabled (F3=1), the user alarm output will activate
when the flow rate is greater than the flow rate maxi-
mum threshold value. The user alarm output is also
active if the flow rate is less than the flow rate mini-
mum threshold value for three consecutive samples.
The alarm occurs after three consecutive samples to
avoid alarms when stopping or starting fluid flow.
F4 – Maintenance Totalizer Alarm Enable
If enabled (F4=1), the user alarm output will activate
when the maintenance totalizer reaches the target
value.
F5 – Battery Alarm Enable
If enabled (F5=1), the user alarm output will activate
when the battery voltage falls below the useable limit.
The grand totalizer will be saved to non-volatile
memory.
H1 – Station ID
Set the station ID between 1 – 246. The default setting
is 1. The actual modbus address will be <station ID>
+1.
J1 – Battery Powered Operation
If J1 is set to 1, which is the default setting, the
Informer display will go into sleep mode after 5 min-
utes without any activity on the keypad. This helps
conserve on battery power. If J1 is set to 0, the
Informer display will never enter sleep mode so it is
always available to respond to Modbus communica-
tions requests and external Batch Reset inputs. When
the J1 parameter is displayed the battery icon will
flash.
Calibrating the Meter
1. Enter Setup Mode by holding down the enter
button , then pressing the up arrow button .
2. Set the Maintenance Totalizer Units [b1] to “cc”.
See page 17.
3. Set the K-factor [E1] value to “1.000”. See
page 18.
4. Hold down the enter button , then press the up
arrow button to exit Setup Mode.
5. Press the enter button to display the Mainte-
nance Totalizer value.
6. Reset the Maintenance Totalizer value by pressing
the reset D button for about one-half second.
7. Dispense at least 500 cc of material through the
flow meter into a graduated cylinder or beaker.
8. Read the Maintenance Totalizer value.
9. Calculate the new K-factor (cc/pulse) value by
dividing the measured volume of dispensed
material by the value of the Maintenance Totalizer.
K-factor = dispensed volume / Maintenance
Totalizer.
10. Enter Setup Mode.
11. Set the K-factor [E1] value to the calculated value.
12. Verify calibration by exiting Setup Mode, resetting
the Maintenance Totalizer, dispensing material,
and comparing the volume of the dispensed mate-
rial with the displayed value of the Maintenance
Totalizer.
