CKW-55 CHECKWEIGHER

3.5 Application Modes

Before using the CKW-55 Indicator, make sure it has been properly set up and calibrated (refer to Sections 3.3.2 Menu
Navigation and Section 3.6.1 Setup Menu).
If the unit is received as a scale, it has been factory calibrated and can be operated at this point using the factory default
settings. To ensure optimal accuracy, Ohaus recommends that the Scale be re-calibrated before use (refer to Section 4.1 for
Calibration and Appendix B Legal for Trade Sealing if required).

3.5.1 Weighing

Zero Operation

Press the ON/ZERO Off button to zero the weight display. The scale must be stable to accept
zero operation.

Basic Weighing

Place the item to be weighed on the Scale platform. The illustration indicates a sample of
1.5 kg, Gross weight.

Manual Tare

When weighing an item that must be held in a container, taring stores the container weight
into the Indicator's memory. Place the empty container to be tared on the scale platform
(example 0.5 kg).
Press the TARE button. The container weight is tared. The display will show 0 kg, Net
weight.
To clear the Tare value, empty the scale platform (the display will show the tare weight as a
negative value). Press the TARE button. Display will show 0 kg, Gross weight.
Pre-Set Tare
A Pre-set Tare (PT) is a known tare value entered through the numeric keypad. The PT value
will supersede any other Tare or PT value in memory. (When using Pre-Set Tare, make sure
that Auto-Tare function is set off in the Setup menu.)
To initiate a Pre-set Tare, enter a numeric value using the keypad (example 1.000 kg), then
press the TARE button.
Display will show the Pre-set Tare as a negative value, with the PT indicator on.
Notes: 1.If the TARE button is not pressed 5 seconds from the last numeric entry, the
display returns to the previous mode without a tare being stored.
2.To clear a Pre-set Tare value, empty the pan then press the TARE button.
The display will return to 0 kg, Gross weight.
