6. The rezero function is used to remo

ve a

calibration offset when hooks or chains are

used to hang the test weights.
• If no other apparatus was used to hang the

test weights during calibration, remove the

test weights and press

RIGHT

to return to

the CALIBR menu.

• If hooks or chains were used during

calibration, remove these and the test

weights from the scale. With all weight

removed, press

ENTER

to rezero the scale.

This function adjusts the zero and span

calibration values. The indicator displays

°CAL°

while the zero and span calibrations

are adjusted. When complete, the adjusted

A/D count for the zero calibration is

displayed. Press

ENTER

again to save the

rezero value and return to the

REZERO

prompt or use the procedure shown in

Figure 4-2 to edit the value. When done,

press

EDP Command Calibration

To calibrate the indicator using EDP commands, the

indicator EDP port must be connected to a terminal or

personal computer. (See Section 2.3.3 on page 5 for

EDP port pin assignments; see Section 5.0 on page 22

for more information about using EDP commands.)

Once the indicator is connected to the sending de vice,

do the following:

1. Place the indicator in setup mode (display

reads

CONFIG

) and remo ve all weight from

the scale platform. If your test weights require

hooks or chains, place the hooks or chains on

the scale for zero calibration.

2. Send the WZERO EDP command to calibrate

zero. The indicator displays

°CAL°

while

calibration is in progress.

3. Send the WVAL command to enter the test

weight value in the following format:

WVAL=nnnnnn<CR>

4. Place test weights on scale equal to the

specified WVAL.

5. Send the WSPAN EDP command to calibrate

span. The indicator displays

°CAL°

while

calibration is in progress.

6. To remove an of fset value, clear all weight

from the scale, including hooks or chains used

to hang test weights, then send the REZER O

EDP command. The indicator displays

°CAL°

while the zero and span calibrations are

adjusted.

7. Send the KEXIT EDP command to e xit setup

mode.

.

3. Revolution uploads calibration data from the

indicator then presents the information in a

display like that shown in Figure 4-3.

4. Enter the

to be used for

span calibration then click

OK

.

5. The Zero Calibration dialog box prompts you

to remove all weight from the scale. Clear the

scale and click

OK

to begin zero calibration.

NOTE: If your test weights require hooks or

Place tests weights on the scale then click

OK

.

7. The Rezero dialog box prompts you to remove
