Job or Grand Total Channel A or B
The FEM-03 displays the JOB or GRAND total for channel A or B based on the KFTs, engineering units,
and decimal locations. The initial total display is JOB total, which shows the current total accumulating in
TOTAL A or TOTAL B. GR TOTAL is the actual real-time sum of JOB total plus the current value of the
GRAND total. View the Grand totals from the TOTAL display. Use SEL to switch between the TOTAL and
GR TOTAL. After a power cycle, the FEM-03 reverts to the JOB.
TOTAL A or B RESET
Use the RESET key DN to re-set job totals anytime while in TOTAL A or TOTAL B. Use the MODE key UP
to select any TOTAL A or B display. Press [RESET] DN to reset any job TOTAL to zero. Simultaneously
reset both JOB A and B totals while viewing the TOT A TOT B screen or at any time using the external
RESET TOTAL input. Momentary closure of terminal DN 6 RESET TOTAL with terminal DN 7 DC COMMON
resets all JOB totals on closure and resumes totalizing upon opening the connection. You can also reset
the JOB Totals using the serial port (see Variable Addressing and Serial Command Variables on page 37).
GR TOTAL A or B RESET
From the front panel, use a multiple-key entry sequence to reset Grand totals. Or reset via serial
command. Individual reset only.
To reset GR TOTAL A or B, use the MODE key UP to select TOTAL A or TOTAL B. With SEL, change to the
GR TOTAL display. Press the RESET and ENT keys simultaneously, and hold until the FEM-03 responds. A
warning appears on the screen requesting yes/no verification before you can reset the GR TOTAL. The
FEM-03 prompts you either to press the ENT key to accept the default answer of NO and exit the reset
procedure at this point, or to reset the total. To reset, use SEL first to toggle the response to YES, then
press ENT. This operation resets GR TOTAL to zero. See Variable Addressing and Serial Command
Variables on page 37 for serial reset of GRAND Totals.
TOTAL and GR TOTAL Rollover
FEM-03 JOB totals rollover to zero when the total reaches a value of 999999 regardless of the decimal
location. When a JOB total rolls over or is reset, the contents of the JOB total are then added in memory
to the GRAND total but not immediately to zero. To allow retention of the largest possible GRAND total
before data loss, after reaching a value of 999999, regardless of decimal location, a floating decimal
