TROUBLESHOOTING
Your scale has been precisely calibrated at the factory before shipping. It has the capability to adjust its own calibration to a certain
degree to compensate for aging electronics, and temperature changes. This being the case, it is possible that you will never have to
calibrate the scale. Doing so may leave you with a worse calibration than you started with. Does your scale really need to be
calibrated? If so what steps are needed? Follow the steps outlined below to help make this determination.
Scale reads zero and will not move.
❑
Make sure that any and all shipping screws are removed from the platform.
❑
On platform scales, check that all four level legs are contacting solidly against the floor.
❑
If level legs are screwed in all the way then the stud from the level leg may be contacting the underside of the platform not
allowing the load sensor to flex.
❑
Check to see if the SAW platform is securely connected to the Digital Indicator.
❑
Check
SAW Diagnostics
and see if all the numbers shown on this screen are constantly moving. If any of the numbers is
showing 0.000, please call customer service for further assistance.
❑
Perform a Full Power cycle (disconnect the scale from the outlet) and then perform a
SAW Cap Zero.
❑
Perform
“Restore to Factory Defaults”
to fix the issue.
Scale reading is fluctuating wildly.
❑
Scale must be on a non-vibrating surface. Breezes may affect scales of all capacities. Breeze/Wind is much worse than
vibrations because wind is additive. It is difficult to filter out the wind added noise. The scale must be put in an environment
where wind is not a factor.
❑
Scale must be installed on a clean power line. Electric motors, computers or any other devices can cause power line
interference.
❑
RF interference can cause scale readings to fluctuate. Are there any transmitters nearby like cell phones or walkie-talkies?
❑
If the scale is a remote platform type, check to see if the cable from the platform to the indicator in plugged in properly. If so
then remove the plug temporarily to check for bent or missing pins.
❑
Check for nicks or cuts on the platform cable.
❑
Perform a Full Power cycle (disconnect the scale from the outlet).
❑

❑

❑
Perform
“Restore to Factory Defaults”
to fix the issue.
Scale reading is different on different areas on the platform?
❑
On platform scales, check that all four level legs are solid against the floor. If a level leg is screwed in all the way then the stud
from the level leg may be contacting the underside of the platform not allowing the load sensor to flex.
❑
Check for any mechanical interference. Is there anything rubbing against the platform?
❑
Perform “
Restore to Factory Defaults
” to fix the issue.
Scale corners properly but does not indicate the correct weight.
