SOLO 1000® Online Trouble-Shooting Guide

SOLO 1000 ELECTRONIC SCALES: Our electronic scales sense weight through a shear beam strain gauge load cell mounted in a hardware assembly beneath the platform. The shear beam load cell accepts load at one end of the beam and thus deflects (or strains) a Wheatstone bridge within the load cell. This deflection causes a change in microvoltage (millivolt / volt signal) proportional to the applied load, which is displayed as a weight or volume on our multi-channel digital weight indicator.

Symptom: DISPLAY WILL NOT CHANGE
Possible Cause: LOAD CELL / TARE ADJUST KNOB WIRING
This condition can be caused by an improper installation (single channel or dual channel). When the scale is initially installed, the load cell cable is sometimes disconnected from the SOLO so that it can be run through conduit or a hole in a wall. When reconnecting, you must make sure that both the Load Cell Cable and the Tare Adjust Knob are connected to the same J1 connector terminal. If the Tare Adjust knob wires have not been reconnected properly to Red, Green and Black, this will sometimes cause the display to lock-up.

Symptom: ERRATIC READINGS
Possible Cause: FRICTION OR BINDING
For any scale to operate properly, plumbing or other devices must not restrain the tank or platform. In order to eliminate any friction or binding in the system, all tank supply or feed connections must be flexible. If there is any friction or binding in the tank connections, fluctuations in readings may happen due to the load cell being restrained from moving up and down freely as temperature and weight changes.
