CALIBRATION
Recommendations
After familiarizing with various features and options available with the SAW Scale, please place the scale in the environment where the
scale will be mostly used to get the scale acclimatized with its current environment. Take into account that the scale needs to warm up
time of 10-15 minutes after boot-up.
Overview
❑
Before performing any calibration, the scale must undergo a Full Power Cycle. This means disconnect the scale from the
power supply, wait a full minute, and then reconnect it back to the power supply.
❑
Once the scale is back on, allow 5-10 minutes of warm up time for initialization and stabilization. Do not operate the scale
during this period.
❑
The scale is ready to be used. If accuracy is an issue, proceed to the next step.
❑
If the weight reading is off, perform
Full Calibration
as described below. Take note of any errors that may occur during this
time. If the Calibration results in an error, refer to the
Troubleshooting
section for solutions. It is strongly to power cycle the
scale once an error is encountered. This allows calibration to take place in a fresh state.
❑
If the Calibration fails repeatedly, or if problems with weight do not get resolved through Calibration, refer to
Restore to
Factory Defaults
to restore working factory parameters that are built into the scale.
SAW SCALE FULL CALIBRATION
If the scale is not showing accurate values for a given weight on the platform, perform a Full-Scale calibration as described below.
1.
Scroll to PLATFORM SETUPS and press ENTER.
2.
MENU button (#5) ---- setup menu screen will appear
3.
In the
Platform Setups
Menu, scroll to SPAN CALIBRATION and press ENTER.
4.
The next warning message warns you about the consequences of performing an incorrect calibration. Read the warning
message, and then press ENTER
5.
Input the calibration weight on the space provided. The calibration weight must be at least 50% of full capacity. If you make a
mistake, press ZERO until the mistake clears.
6.
Press ENTER to confirm input of calibration weight.
7.
Remove all weight from the platform. The current weight is shown at the top left side of the screen. Make sure that the
reading is as stable as it can be. Then press ENTER.
8.
Wait for the next prompt to appear.
9.
When the prompt appears, place the known weight on the platform.
10.
Wait for the raw count on the top left side of the screen to stabilize (about 5 seconds). Press ENTER to confirm the placing of
weight.
11.
Wait for a few seconds until the calibration procedure completes.
12.
Press MENU/BACK to go all the way back to the weight screen.
If at any time you received an error while performing this calibration, you must do a hard reboot of the scale (unplug the power
adapter out and then plug it into the outlet again) to retry the calibration. See the
Troubleshooting
section for description of errors.
