Calibration
Warning:
You cannot change the legally related parameter values and calibration after sealing the
instrument in legal usage. Be sure the proper adjustments you done before sealing the scale.
Scale definition
Before the calibration can be performed the capacity and resolution of the scale must be defined.
Press
key at the [ 523 MAX / d] prompt and set the required capacity and resolution of the scale.
Then continue with the following:
Calibration involves emptying the scale then placing a known test weight on an empty platform and
allowing
FT-112(D) Panel to capture values for zero and span. Calibration is performed as;
1. Press
key at the [ 611 TEST WEIGHT
]
prompt to start the calibration.
2. At the [
UNLOAD THE PAN]
prompt, remove any weight on the platform, then press
key.
3. The terminal automatically starts to capture zero and the [ WAIT ] message appears during zero
adjustment.
4. The test weight value will be used for the calibration is shown on the display as [
LOAD THE SCALE
]
[ XXXXXX ] after zero adjustment. Enter the test weight value via numerical keys. A minimum test
load requirement is 20% of scale capacity for accurate calibration. FLINTEC recommends test load
between 50% to 75% of the capacity.
5. Place the test weight on the scale.
6. Press
key to start span calibration. [ WAIT ] message will shown on the display 10 seconds while
span calibration is being performed.
6.5.1 Linearity Correction
Multipoint calibration in this parameter improves the scale performance.
1. Press
key at the [
612 LINEARIZATIO
]
prompt to start the calibration.
2. At the [
UNLOAD THE PAN]
prompt, remove any weight on the platform, then press
key.
3. The terminal automatically starts to capture zero and the [ WAIT ] message appears during zero
adjustment.
4. At the [
LOAD 1
]
[ XXXXXX ] prompt, the test weight value will be used for the first step calibration is
shown on the display. A test load requirement is between 35% to 60% of capacity. Load the scale and
enter the test weight value via numerical keys.
5. Place the test weights or another practical weight on the scale.
6. Press
key to start span calibration. [ WAIT ] message will shown on the display 10 seconds while
the first span calibration is being performed.
7. At the [
LOAD 2
] [ XXXXXX ]
prompt, the test weight value will be used for the second step
calibration is shown on the display. Place test weight on the platform at least 90% of scale capacity,
preferable at scale capacity. Enter the weight value by numerical keys.
8. Press
to start second step span calibration. [ WAIT ] message will shown on the display 10
seconds while the span calibration is being performed.
