7.8 DIP Switches
DIP switches are located inside the instrument on the mother board. The switches are in the
"on" position when they are switched towards the "ON lettering printed on the face of the
switch (towards the top of the instrument). With the switches at the bottom left of the board,
the order from left to right is SW1.1, SW1.2, SW2.1, and SW2.2.
Dip Switches control the following:
SW1.1 - Cal Protect: Protects calibration from changes in the device setup menu. Values can
still be viewed, but an attempt to modify these settings will cause the device to briefly show
a "dIP" message (see Figure 7.3
SW1.2 - Backlight Always On: Forces the backlight into the always-on state and will no
longer turn off under bright ambient lighting conditions. This will significantly reduce bat-
tery life.
SW2.1 - Cal Expire Timer: Enables calibration expiration timer feature (see Calibration Ex-
piration Lockout on page 56). The due date for the calibration can be programmed through
software. When the due date has passed, the device will lock out of normal operation if this
is enabled. Software will be required to reset the calibration expiration date. This causes the
"CAL" fault (see Figure 6.5).
SW2.2 - N/A: Reserved for future use.
