2. Main functions and instructions:
Skin removal function (TARE):
When the display value is more than 2% of the full range, press this button to peel.
Unit Conversion Function (UNIT):
The keys can be switched to the next unit in turn for each operation. A total of 13 measurement units are available: g/ct/Ib/oz/dr/gn/oz t/dwt/MM/tl.J/tl.T/tl.H/t;
Counting function (PCS):
The number of samples is calculated according to the sampling ratio of a single weight.
Mode Function (MODE):
(1) Each button press can be switched in three modes in turn: number counting mode, percentage counting mode and weighing mode.
Zero clearing function (ZERO):
When the display value is less than 2% of the full range, press this button to zero.
Intelligent backlight;
Printing function;
Alarm prompt;
Third, parameter setting: press the "MODE" key to enter the setting;
MODE: Confirmation key;
ZERO: Select key;
1. Backlight setting: AUTO BLK (automatic backlight), ON (constant light), OFF (off);
2. Printing settings: 1CoM, 2CoM, 3CoM, (1 stable output, 2 automatic output, 3 manual output)
3. Baud rate setting: 9600, 2400, 4800;
Fourth, the method of use:
Pre-heating: Turn on the switch and turn on the power. The scale display scrolls from full brightness,'0000000'to'9999999'. The product model is displayed later,'0.00', and then preheat for more than 15 minutes to make the weighing accurate.
Correction: If correction is needed, the scale should be preheated for more than 15 minutes and displayed as "0.00". If the zero deviates, the TARE key can be pressed to stabilize the zero of the scale. After "ZERO" 5 seconds, the "CAL and calibration scale" can be displayed, the standard weight can be placed to display the internal code, and the "PASS" - Calibration weight can be displayed after stabilization, then the correction is completed.
When weighing, if the weight of the weighed object exceeds the full weight of the scale + 9d, the scale will display the overload indicator "HHHHH" and send out an alarm sound.
Peeling: If the indicated value deviates from zero or weighs the load on the disk, the peeling key should be pressed to make the indicated value return to zero.
Counting: Put the sample on the weighing plate and press the "MODE" key to select the counting mode. There are two counting modes to choose from: 1. "PCS" (number mode) and 2. "PCT" (percentage counting mode). At this time, the scale shows the weight of the sample. Press the "PCS" key to flicker to display "100pcs", press the "TARE" key to increase or press the "ZERO" key to reduce the value until the display number is the same as the sample number, and then press the "PCS" key to confirm the sample number. At this time, the object to be measured can be placed on the weighing plate, which shows the number of scales. If you want to exit the counting state, just press the "MODE" key to switch to the weighing state in turn.
V. External calibration:
1. Press "ZERO" button for 4 seconds and release it after flash calibration.
2. Put the corresponding calibration weights on it and automatically display the "PASS" calibration after stabilization.
6. Linear correction:
1. Start-up auto-return to zero state, press TARE key for 3 seconds, automatically enter the zero-bit internal code interface, wait for the stable symbol, press (MODE) key, display the first paragraph internal calibration, (flicker state) wait for the stable symbol, put the weight corresponding to the gram, then the second paragraph positive value flickers, take down the first paragraph weight, put the second paragraph correction value weight, the same kind of operation. Four times,
Notes:
It must strictly comply with the technical requirements of the machine.
The scale must be placed on a flat and stable platform, in a non-vibration, non-strong airflow, no thermal radiation, no strong electromagnetic field environment.
After startup, if the display is unstable, check whether the weighing plate is put in place, whether there is collision or obstruction.
Do not need to be charged before storage. The battery should be charged once every two months. The service life of the battery can be prolonged by the alternation of external power supply and battery.
7. RS232 Communication
The balance is equipped with standard RS232C data output interface, which can directly connect 16 pins of micro printer. Press the "PRINT" key on the balance to print data (printer settings can refer to the following). If you need to connect with the computer, you should compile the sampling software in the following format.
1. Wiring method
Computer (printer) balance
Prefix = V ns = urn: schemas-microsoft-com: VML
2. Transfer Format: Serial Asynchronous Communication
3. Serial Communication Protocol: Baud Rate = 9600
Data Bit 7 Start Bit 1 Stop Bit 1 Bit (No Check)
4. Data Format: Spaces/-Data Unit Symbol Enter
1 bit 7 bit 2 bit 1 bit
All the above characters are ASC II codes. One of the seven bits of data is decimal point, and the six bits without decimal point. The unit is the display unit of electronic balance.
8. Error Information and Troubleshooting
If the startup does not show, first check whether the voltage regulator power supply has electricity or whether there is a fault.
If the self-test does not return to zero, it means instability. Check whether the weighing plate meets? Whether the use environment has an impact.
It shows that HHHHH indicates that the weighing is greater than 9D of full range and that the weighing is overloaded. Some items should be removed until they are weighed properly.
