• If you do not get a reading from one of the
load sensors, either the cable to the load
sensor is disconnected or the load sensor is
malfunctioning.
• If one of the load sensors is reading higher
or lower than the other load sensors in
your system and you know that you cali-
brated the instrument and cornered the
scale, there is something wrong with the
load sensor.
• If one of the load sensors is reading higher
or lower than the other load sensors and
you do not know if the scale has recently
been calibrated, re-calibrate the scale then
check the Voltages and Weights again.
Stability Test
The Stability Test switches a fixed signal into the analog to
digital convertor, and calculates the mean squared variation
from the average reading, using 100 samples.
The test passes if the mean squared variation is less than 5.0,
and the average reading is between 30237 and 36955.
NOTE: Before performing the Stability Test check to see
if all the Channels have been enabled from the
Web Browser.
Step 1. Press the up or down arrow buttons until the cursor
is in front of Stability Test. (See Fig.7-109)

• The results of the Stability Test are dis-
played for this scale as PASS. (See Fig. 7-
112) This means that the Mean Squared
Variation is less than 5.0 and the average
reading is between 30237 and 36955. In
short the instrument is working fine.
