Appendix A: About Bi-Directional Communication INSTALLATION Because of metrological legislation, installation/some metrological parameter settings are limited to be done by authorized personnel only. Do not attempt to change any of the built-in metrological parameters. Contact your dealer for more information and technical assistance. To ensure performance accuracy, do not use the instrument in where or when the environment condition falls beyond as those listed on SPECIFICATIONS.

4. GETTING STARTED In order to obtain accurate weighing and counting result, the instrument must be placed on a strong and level surface horizontally. Avoid using the instrument in environment where excessive wind flow, vibration and extreme temperature change exist. The instrument should be installed CA from any sources of excessive electrical noise. For full EMC or for RFI immunity, termination of cable shields and correct grounding of the instrument is essential.

INITIAL SETUP 5.1 INTERNAL SETTINGS Preferred application parameters can be checked or set through internal functions. Refer to 5.
c. The instrument displays F1, d. The instrument is now in internal function, 5.
6. INSTRUCTION FOR USE 6.1 POWER ON Powered on the instrument, instrument displays: a. softCAre and revision number and capacity of instrument, b. calibration count value, c. parameter set count value, d. all LCD segments, Then countdown process starts. After that, the instrument is ready for operation. 6.2 START WEIGHING a. If zero weight cannot be obtained when unloaded, press [ZERO]. After [ZERO] is pressed, Zero Indicator appears. Refer to SPECIFICATIONS for maximum zero range, b.
6.4 TARE OFF THE WEIGHT OF A CONTAINER 1 Tare function is used to temporarily set the instrument to zero (such as cancelling the weight of a box or a container) in order to get the net weight result 6.4.1 Enable / Disable Repeat (Multiple) Tare Depends on internal function setting, repeated (multiple) tare operation may be enable (Mode 1) or disabled (Mode 2). Contact your dealer for more information. When repeat (multiple) tare is enabled: 1.
f. To cancel tare effect, remove all loads and container from platter and press [TARE] , g. Net Indicator disappears. Tare effect has been removed and weight reading is gross weight. 6.4.3 Preset Tare This feature enables the user to manually enter the tare weight. During normal operation, enter the pre-determined tare weight through numeric keys then press [TARE]. This pre-determined tare value will be deducted. To cancel the preset tare effect, remove all loads from platter then press [TARE]. NOTE: 1.
d. To enter new unit piece weight, repeat step b above. 6.5.2 Sampling Process This method is used where unit piece weight is unknown or the weight of individual piece is not highly standardized. a. Refer to 6.2 and 6.4 for zero, selecting preferred weight unit and tare operation, b. Place a sample size with known quantity on platter c. Enter the quantity of the sample through the numeric keypad and confirm by pressing [# SET]. d.
b. The quantity added to platter is less than 100% of the maximum counts previously attained from the same transaction. If the above requirements are fulfilled, a new unit piece weight will be determined and displayed on the Unit Piece Weight Panel and confirmed by 2 audio beeps. Auto Unit Piece Weight Enhancement Function will terminate when: a. a zero weight is detected or during the transaction process, or b.
10 c. output transaction printout(s) through the RS232 comport. The instrument returns to normal operation status after 2 seconds, 11 Repeat a for subsequent transactions , 6.7.2 Memory Recall and Clearance a. Remove all loads from platter, b. Press [M+] to recall total accumulated weight from memory, c. After [M+] is pressed, the instrument displays: d. The instrument displays: “ACC” on Weight Panel. “n” on Unit Piece Weight Panel.
Hints: 1. For normal comparison, set both HI and LO limits, 2. To check only if result is lower or equal to LO (result ≤ LO), set HI limit = 0, 3. To check only if result is higher or equal to HI (result ≥ HI), set LO limit = 0, 4. To check if result is equal to a specified value, set both HI limit and LO limit = the specified value 6.8.2 Visual and Audio Quantity Check Signals 6.8.2.1 Visual signal: - Quantity check result is displayed by one of the Check Result Indicators located on Quantity Panel. 6.8.
7. RS232 DATA OUTPUT Data output parameters are fixed as below: Data Bit = 8 Parity = None Stop Bit = 1 13 There are 2 data output modes (PC and Prt) are available . PC is for communication with computer and other peripherals which accepts and processes continuous data communication. Prt (printer) is for transmission to printer or other peripherals which accept only single or manual data transmission. Baud rate has to be set before proceeding to other settings. 7.
