To set a value greater than 99999, press the RECALL button causing all the decimal points to light,
indicating that the displayed value must be multiplied by 10. Thus, any value up to 999990 can be set.
NOTE: If the most significant digit (that on the extreme left) is zero, you cannot set the times ten
mode.
To escape from the EDIT Mode at any time without updating the value, simply press the RESET
button.
To exit from the EDIT Mode and update the value, press and hold down the SET button and then
press the RESET button. Always ensure that the value entered is within the constraints laid down or
you will get an Err 7 message, and the value will not be updated. Err 5 will be displayed if you try to
set a limit that is not enabled. If the value is acceptable the unit will display donE.
NOTE: Any time the limit value is changed, the instrument will automatically recalculate the hysteresis
at 5%. Refer to Sections 6.8 and 6.9.
5.1 Edit Mode Button Summary (Changing Digits)
When in the EDIT Mode as described above, the keypad buttons have the following functions:

6.3 SET 1 (Alarm 1)
NOTE: This menu option will not be seen on an ACT-2A.
Used to set the LIMIT 1 type. This menu item has a number of sub items. HI or LO determine
whether the limit is high or low, LATCH or RESET determine whether the limit will be latching
or non latching, and LOC or NOLOC determine whether the lock out feature will operate for the
LO limit setting.
Select this item with the SET button. You can exit back to the main menu at any time without
changing the current settings by using the RESET button. Once selected, the display will show
the current setting of the limit type. If no limit is set it will show OFF. You may cycle through
the three choices (HI, LO, OFF) by using the UP (
∧∧∧∧∧) button. Press the SET button when the
desired limit type is displayed.
The unit will then display LATCH or RESET depending on how it is currently set. Again, use the
UP (
∧∧∧∧∧) button to change the type. Pressing RESET at this time will not alter the limit. Use the
SET button to continue. If you set the limit to HI, you will return to the main menu. If you
selected LO, you will have to choose the LOC or NOLOC option as described above.
NOTE: Setting the limit type will force a recalculation of the hysteresis to 5%.
6.4 SET 2 (Alarm 2)
Same as SET 1 but for LIMIT 2.
6.5 SERNO (Serial Number
Used to view the serial number of the unit. Use the SET button to view the serial number and the
RESET button to return to the main menu.
6.6 SCALE (Scale Factor)
Used to set the scale factor for the Scale Mode of operation. This menu option will not be seen
if the unit is not set in the Scale Mode. Enter this menu item with the SET button. The current
scale factor will be displayed. To exit to the main menu without changing the value press the
RESET button or else change the value in the same way that the limits are changed, as in Section
5.0. To update the scale factor, press the SET and RESET buttons. The permissible values for
the scale factor are from 0.0001 to 9999.9.
6.7 TOTAL (Totalizer Scale Factor)
Used to set the scale factor for the Totalizer mode of operation. This scale factor is independent
of the SCALE mode scale factor. It will not be seen if the unit is not set in the TOTAL mode, using
the TYPE menu option. Enter this menu item with the SET button. The current Scale Factor will
be displayed. To exit to the main menu without changing the value press the RESET button, else

6.8 HYST1 (Hysteresis Limit 1)
NOTE: This menu option will not be seen on an ACT-2A or if the limit has been set as non-
latching.
Used to set the limit hysteresis as a percentage. Once selected with the SET button, the existing
hysteresis value will be displayed. It may be changed in the same manner as setting a limit. Refer
to Section 5.0 and 5.1. The permissible values for hysteresis are 0.0001 to 99.999%. The RESET
