Setup Menu - GF Signet 2551 Operating Instructions Manual

Setup enu
The Setup menu contains all of the parameters necessary for the 2551 Magmeter to begin
measuring fl ow.
NOTE: The Security Code must be entered before any changes can be made to the Setup menu.
See page 17 for details related to the Options menu..
Use the keypad to navigate through each setting.
ENTER
K-Factor: See the charts on pages 12-13 for values in pulses per U.S. gallon or in pulses per liter.
To use other units, convert the published values as appropriate.
Pipe Size: Select the pipe size that is nearest to the nominal pipe size.
Flow Units: Set the units for the application. Four characters are available. The fi rst three characters can be set to any symbol or alpha
character, upper or lower case. The following special symbols are located between the upper case and lower case menus:
• (centered dot) μ (micro)
- (dash) / (slash)
The last character selects the timebase for the fl ow rate measurement.
Select S/s (seconds) M/m (minutes), H/h (hours) or D/d (days)
Set 4 mA: (2551-22 and -42 versions only) Set the fl ow rate where the current output will be 4 mA.
Set 20 mA: (2551-22 and -42 versions only) Set the fl ow rate where the current output will be 20 mA.
The 4 to 20 mA output may be spanned to monitor forward and reverse fl ow rates.
Total Factor: Set the factor by which the totalizer will count. This setting is made in the application
units (i.e., gallons, liters, etc.)
Totalizer Units: Set the Totalizer Units. This setting serves as a label for the totalizer displays only.
It has no effect on the measurement. The special characters listed in the Total Factor settings are
available here also.
Low Flow Cutoff: Set a fl ow rate that the 2551 Magmeter will use as a minimum threshhold.
If the fl ow rate falls below this value, the 2551 will respond as if the fl ow were zero.
Averaging: Set the averaging period based on the installation and fl ow conditions. Smaller values
allow the 2551 to respond to changes in fl ow rate quickly, while larger values smooth the fl uctuations
caused by installation and fl ow conditions. See page 11 for details.
Sensitivity: Set a percentage of maximum range by which the fl ow must change to override the
averaging feature and "jump" quickly to the new fl ow rate. See detailed explanation on page 11.
