How to Perform an Electronic Calibration
Menu Code 27
This Menu Code is used to calibrate the meter.
WARNING!
Perform the E-Cal prior to dispensing fuel. If the E-Cal is not performed
properly, the dispenser will produce a Calibration error.
How to Program the Dispenser for Operation
Prior to entering Mode 27 slide the switch over on the
CPU Board. Currently this switch is in “Normal Operating
Mode”. To gain access to Mode 27 slide it to the right
anytime before going into this mode. If attempting to dis-
pense with this switch in “E-Cal Mode” the dispenser will
give an Error 74.
The Calibration Procedure
Prior to performing any E-Cal procedure go to Mode 6
and make sure the dispenser configuration is correct.
Also make sure that every product has a price other than
zero. A zero price will prevent the use of any configured
meter.
To perform a Direct Percentage calibration, follow this
procedure:
1. After the Manager’s Mode has been accessed, press
the number
2
and
7
, then the
MODE
button on the
keypad.
The first display shows the current electronic cali-
bration correction constant of the configured me-
ter. See Figure 27.1.
Use the
↑
(up arrow) button or the
↓
(down arrow)
button to view the current electronic calibration
correction constant for each configured meter
(product A or product B). Once you are viewing
the desired meter, press
Enter
.
The main display now shows the direct percent-
age entry menu as shown in
Figure 27.2.
2. Enter the direct percentage value needed to calibrate
the dispenser and press
Enter
.
As the new electronic calibration correction constant
is entered, it will show up in the main mass display
(see figure 27.2). When the Enter button is pressed,
the entered electronic calibration correction constant
is loaded into the current meter and appears in the
second PPM display.
3. Press the
Cancel
button to return to the current elec-
tronic calibration correction constant of the first con-
figured meter.
4. Press the
CANCEL
button to exit this menu.
