SETUP AND CALIBRATION, Cont.
12. After a few seconds, the screen will prompt:
CAL WT 2, the second of two calibration
weights and display the current setting. If the first calibration weight was ZERO or NO
LOAD, this weight should be equal to the test weight total. If, however, the first weight was
the test weight total, then this weight should be zero.
If this second calibration weight is to be zero, make certain the scale platform is empty,
use the keypad to input a 0, then press the
ENTER
key. If this second calibration weight is
to be the test load, use the keypad to input the value of the calibrated test weights. Place
the weights on the scale platform, then press the ENTER key.
13. After a few seconds, the screen will prompt:
FINE SPAN ADJUSTMENT. Place a
known weight on the scale. Any small error will be displayed and can be corrected as
follows:
Press the UP key to increase displayed weight 1 grad per press.
Press the DOWN key to decrease the weight 1 grad per press.
Press the ZERO key to zero the scale.
Press the EXIT key to save the settings and proceed to the next step.
14. After a few seconds, the screen will prompt:
SCALE X CALIBRATED (x = scale
number), indicating the setup and calibration process has been completed. The "C"
numbers will be displayed and should be recorded for future use. After recording the "C"
numbers, press the EXIT key. The instrument will reset, display the Start Menu and then
advance to the Weight Screen. Replace the calibration sealing screw on the scale input
board, and proceed with normal operations.
NOTE:
Changes to the 777 setup parameters can be performed WITHOUT affecting
the calibration. This is accomplished by entering the changes necessary up to the
screen prompt
C1
and pressing the ENTER and FNCT keys. That is, follow the
standard Setup and Calibration procedure up to the screen prompt,
C1. Then
instead of entering a value for C1, press the ENTER key, then at the
CAL WT 1
prompt, press the FNCT key. The instrument will reset, display the Start Menu and
then load the application program or standard program. Replace the calibration
sealing screw on the scale input board, and proceed with normal operations.
This allows inputting new Setup parameters, without the need to re-calibrate the scale.
LOADING AND SENDING PROGRAMS
The 777 Programmable Weight Indicator can receive and send application programs to and
from another 777 indicator or with the optional SmartWeigh software development package to
and from a computer.
To transfer application programs between 777 indicators, one indicator must be in the Receive
mode, the other in the Send mode and a 8545-B099-0A (778 to HOST PC) transfer cable must
be connected from the COM port of one indicator to the COM port of the other indicator.
To transfer application programs between the computer and the 777 indicator, the SmartWeigh
program must be loaded and running on the computer, and a 8545-B099-0A
(778 to HOST
PC) transfer cable connected between the COM port on the computer and the COM port of the
777. The indicator and the SmartWeigh program must be in the appropriate modes (one in
send, the other in receive) to transfer application programs. Refer to the SmartWeigh
Programming and Simulator Manual (8545-M095-O1) for operation of SmartWeigh transfer
procedures.
