Calibration Test - OHAUS CKW-55 Instruction Manual

CKW-55 CHECKWEIGHER
After a few seconds, the requested Full Scale calibration value and unit flashes on the display.
This is a fixed value based on the full scale capacity and cannot be changed.
(This sample illustrates a Full Scale Linearity Calibration value based on a Full Scale Capacity
and Calibration Unit setting of 30 kg.)
Place the corresponding mass on the scale platform, then press the Yes button. -C- is
momentarily displayed while the reading is stored.
If calibration was successful, the calibration weight is displayed and the scale exits
automatically to the active weighing mode. Remove the weight and begin weighing operations.
Remove the weight and begin weighing operations.

4.1.3 Calibration Test

This menu item is used to compare a known calibration mass against the calibration data stored by the Scale. When any
selection within the Read-GMP menu is enabled, calibration test results are automatically printed.
Note: The Calibration Test function is available even when the CAL menu is locked out.
Press the GNT Menu button until MENU is displayed, CAL will be displayed. Press the Yes
button to enter the CAL menu. Repeatedly press the No button until the sub-menu item CALTST is
displayed. Press the Yes button and initiate Calibration Test.
The display flashes 0, indicating that no weight should be placed on the platform at this time.
After ensuring that the scale platform is clear, press the Yes button. -T- is displayed while the
zero point is measured.
The display flashes the calibration test mass.
If a different calibration test mass is desired, enter the new value via the numeric keypad, (whole
numbers only). (The example illustrates a new value of 10 kg.)
Place the corresponding test mass on the scale platform and press the yes button. -T- is
momentarily displayed while the data is measured.
The display now indicates (flashes) the actual difference between the stored calibration data
and the test mass data. (This example illustrates a 0.010 kg difference.)
After approximately 5 seconds, Calibration Test ends. If enabled, the result of the calibration test
is printed. The scale returns to the active weighing mode and displays the current weight on the
platform.
