WI-125 SST Indicator Service Manual
This service manual will help you prepare your WI-125SST indicator for use.
This manual covers the following:
• Introduction
• Operational Modes
• Sealing the Indicator
• Keyboard
• Configuration Mode
The WI-125SST operates in three modes:
• operations mode
• test mode
• configuration mode
Operations mode contains all normal weighing operations. In this mode you
can view or set the following parameters if the unit is so configured:
• pushbutton tare
• quick keypad tare entry
• one to ten tare registers (numbered 0-9)
• identification number
• time
• date
• backlight
Any combination of these items can be secured behind a security code. Any
items secured by the code number can be viewed but not changed. Opera-
tions mode is fully explained in the
User's Manual .
Use this mode to perform tests on the WI-125SST. The test mode is cov-
ered in the
User's Manual .
Use this mode to setup options and program the operation of the scale and
indicator. Configuration is explained fully in the
Configuration Mode section
of this manual.
The WI-125SST can be sealed so no configuration items can be changed in
the configuration menu. Seal an LCD version by placing switch S1-1, located
inside the unit near the bottom corner of the PC board (see Figure 1), in the
OFF position. Unseal the unit by placing S1-1 in the ON
position. For both LCD and LED versions of the indicator,
while the indicator is powered, the state of the switch can
be changed at any time except while in the configuration
menu. If you change the state of the switch then, it WILL
NOT take affect until you exit the configuration menu.

To seal or unseal an LED
version indicator, push the
button that is mounted inside
the rear panel. The only way to
observe the security setting of
