OPERATING INSTRUCTIONS
Automatic OFF
The caliper will turn off (the display will go blank) after 30
minutes of no slide movement or press of a button. A one
second push of either the “in/mm or “zero on/off” button will
reactivate the display. Any movement of the slide will also
activate the display with no loss of position.
In/mm Button
The caliper can be changed from inch mode to millimeter
mode, or the reverse, with a two second push of this
button. When an RS-232 cable is installed in the output
slot of the 798B, the in/mm function is disabled and the
button becomes a send button.
A one-second push of this button will also active the display
with no loss of position.

the display. A one second press of the same button will
also zero the tool at any position of the slide. A three
second push of the button will shut the display off.
Output (798B only)
798B calipers include an output port that allows data
transmission to computers or printers using the appropriate
Starrett cable/adapter or Starrett DataSure® wireless
interface. The output command is controlled by the in/mm
button. 798A models do not include output.

A battery symbol in the lower left corner of the display will
light when the battery is getting weak indicating the battery
should be changed. To replace the battery, follow the
instructions listed under “Installation of Battery”.
