3 Calibration

3.1 Instruction

GM8806A-P6 batching controller need calibrate at beginning of operation or changing any parts on weighing system or non-suitable application for user. The calibration can define radix point, minimum scale division, maximum scale capacity, zero and gain, etc.

User can press to enter next or press to save setting to only change one parameter, and then press to exit.

3.2 Flow chart

Press to display CAL，and then press to enter password.

Input correct password, when display “CAL ON” one second, then enter to set radix point automatically.

(18)

1) Press set radix point (0~0.0000 5 kinds optional), press to save and enter mini division.

2) If not change radix point, press directly to enter mini division.

1) Press to set mini

division(1~50 6kinds

optional)，press to save and enter max. capacity.

2) If not change mini division, press directly to enter max. capacity.

1) Input max. capacity(≤mini division × 30000)，_press

to save and enter millivolt display.

2) If not change, press

to enter millivolt display directly.

1) Select suitable sensitivity

based on load cell,

press to save and enter

millivolt display. Otherwise to press directly to enter millivolt display.

(19)

1) When load cell output millivolt value, press to enter zero calibration directly. 2) The display value is similar with millivolt from SIG+/SIG-terminals. See Character 3.3 for details.

1) When scale platform is stable, press to take present weight as zero，and enter gain calibration.

2 ） Press to reserve

original zero and enter gain calibration.

1) Gain calibration as the left chart.

▲When calibration with

weights, please record zero millivolt, gain millivolt and weight value in list. If no weights, user will calibrate according to these data.

2) Press to enter

password directly, no gain calibration.

1) See Character 5.11 to set

password, then press to

exit calibration and return.

2) If not set password, press directly to return.

(20)

3.3 Millivolt display

This function is mainly used to test weighing system, four-corner position-error of force-transmitted equipment and load cell’s linearity.

1. Test weighing system

(1) If the indicator display variational millivolt value according to add weight, thus indicate load cells are connected correctly and force-transmitted equipment is operated normally.

(2) If the indicator display OFL (or –OFL), thus indicate the weight is too heavy (or too light), then need unload (or add) the weight. But if always display OFL (or –OFL) after changing weight, maybe the following reason cause:

a. Please check force-transmitted equipment. b. Please check the load cell’s connection. c. Please check Load cells.

2. Test four-corner position-error of force-transmitted equipment

Please load same weight on scale’s every corner and record individual millivolt value. If the values are obviously different, please adjust force-transmitted equipment.

3. Test load cell’s linearity

(21)

Please load several same weight values within the weighing capacity and record relevant millivolt value after zeroing every time; if the discrepancy is bigger among millivolt values, thus indicate that the load cell’s linearity is not good, need change new load cell or adjust force-transmitted equipment.

3.4 Calibration without weights

Calibration without weights is only for urgency. If change new load cells or indicator, or adjust weighing system, calibration without weights is not correct.
