Unpacking and Startup
Unpack The Scale Electronics and Base
•Gently remove scale electronics,
remote displays and scale base
from packaging
•Plug the scale in to 110/120 VAC
•If needed - connect to Scale Base
with terminal connection inside
the indicator enclosure.
Scale Base Setup
•Adjust the corner leveling feet until
the level bubble indicates the unit is
level.
•Firmly tighten hex jam nuts on the
leveling feet. (Any time the scale is
relocated, it should be leveled.)
•
Scale Operation
•Press the ZERO button to zero the scale
•Press the UNITS button to cycle

Building a programable data output.
The user programmable data output feature is the string of information sent from the RS-232
port (Or optional Ethernet, Wi-Fi and USB) when the PRINT button is pressed, scale is setup to
auto output or the scale receives an SRP command from a computer or terminal. Select the
format of this string by entering two-digit print codes into the 30 available data output slots,
PSL 81 through PSL 119. When finished entering data to construct the programable data
output, “99”is entered to mark the end of print formatting.
Example: To build a programable data output to send to a printer the following print codes
could be entered
