ZP900 Post Scales User Instructions 19
3.1 Initial power up
3 General operation
When power is cycled or when exiting from a menu the message PoSt is displayed
briefly.
3.1 Initial power up
3.1.1 Power up zero
On power up or when exiting from any menu with SAVEYES selected, the scale must
be within the Power Up Zero window (default is +/- 10%) or a message Z-Error is
displayed. Remove the weight causing the error and when stable the display should
show Zero weight and be ready for normal operation. If the scale will not capture zero
then it may need to be calibrated. Refer to the Service manual or contact the scale
provider if needed.
3.1.2 Power up gravity
If the Power Up Gravity setting was previously enabled the display will prompt with the
message
grAVitY .
Press the ZERO key and the previous setting for the calibration gravity value will be
displayed. This value can be accepted by pressing the ZERO key or enter a new value
to match the installation site location. Use the Numeric entry procedure on page 17 .
The scale should then perform as though calibrated at the installation location. Press
F1 to bypass Gravity entry but this process will be repeated on the next power up until
a value is accepted. Refer to local area Gravitational constants or contact the scale
provider if needed.
3.2 ZERO key
The ZERO key can be used to re-capture zero if the weight is stable and inside the
allowable zero range (default is +/- 2%). If ZERO key is pressed when the weight is
unstable or outside the zero range the message cAnt is displayed.
3.3 F1 key
If a second unit of measure has been configured the F1 key will toggle the display
between the available units of measure. If the second unit of measure is not lb or kg
then the 3rd annunciator along the right side of the display will be illuminated when
active. The
F1 key is also used for password entry to gain access to the ZP900
Configuration and Diagnostic Menu's. Refer to Accessing the menus on page 18 .
CAUTION: Verify with local agencies if adjusting the gravity factor is accepted
in your area. It may be required that calibration be done with certified weights.
