Usage Features:
Front Panel and Status Indicators: The front panel features a 6-digit LCD display and various status indicators.
- AC: Indicates AC adapter is connected.
- Low Battery Warning: A symbol indicates low battery (30% of full charge), and the display blinks when battery capacity is less than 10%, leading to automatic power down after 1 hour.
- Stable Weight: A square symbol indicates stable weight.
- NET: Indicates tare is set and net weight is displayed.
- →0←: Indicates weight is within -1/4e to 1/4e of zero.
- LO, OK, HI: Set point indicators for ranges A≤weight<B, B≤weight<C, and C≤weight<D respectively.
- kg: Weight unit in kilogram.
Keypad Operations:
- 【OFF】: Switches the indicator off.
- 【ON】: Switches the indicator on.
- 【】: Manual weight accumulation.
- 【*】: Proceeds to the next step.
- 【←】: Displays weight to X10 resolution.
- 【→T←】: Tares the display.
- 【→0←】: Zeros the display.
Basic Functions:
- Switching On/Off: Simple ON/OFF operations. Upon switching on, the indicator displays software version and performs self-tests.
- Weight Unit: The default and only weight unit is kilograms (kg).
- Zeroing: Allows setting the zero point when the weight is less than 2% of full scale (FS) and the platform is unloaded.
- Tare Function:
- Acquire Tare: Set tare after zeroing, by placing an empty container on the platform, waiting for stability, and pressing the tare key. The indicator switches to net weight mode.
- Remove Tare: Remove tare and switch to gross weight mode by pressing the tare key when NET status is displayed.
- Simple Weighing: Place sample, wait for stability, and read the weight.
- Manual Accumulation: Accumulate weight manually and transmit data to RS232. The number of accumulated samples is displayed.
- Query Accumulated Data: View the number of samples, upper 4 digits, and lower 4 digits of accumulated weight.
- Clear Accumulation Data: Clear all accumulated data.
- Set Point Function: Configure four set points (A, B, C, D) to trigger LO, OK, or HI status symbols based on weight ranges.
- High Resolution Display Mode: Temporarily display weight with X10 resolution for 5 seconds.
- Automatic Shutdown and Power-Saving Mode: The indicator enters power-saving mode if not operated within 30 seconds, showing "- - - - - -". It automatically shuts down if not operated within 30 minutes.
External Interfaces:
- Load Cell Connectors (CN1): 6-wire connection for load cells, including +E, +S, -S, -E, +Excitation, -Excitation, +Signal, -Signal, and Ground.

- Connecting to a Printer: Provides wiring diagrams for connecting CN5A to a printer's DB25.
- Continuous ASCII Output: When the indicator address (Adr) is set to 00 or 99, it continuously transmits weight data in RS232 ASCII format. Two output formats are available: Adr=00 (X1-X7, S) and Adr=99 (S, X7-X1).
- RS232 ASCII Commands: For Adr set to 01-98, serial communication follows the Modbus ASCII protocol.
- Printer Format: Provides a detailed output format for printing accumulated data including gross, tare, net weight, and total accumulated weight.
