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.
Zero On/Off Button
If the display is off, a quick push of this button will activate 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

button. 798A models do not include output.
Low Battery Indication
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”.
