A9

Product Introduction:

A9 Automobile Scale Instrument

The difference between analog transmission and a9p is that it does not include printing.

Can be connected to an external large screen and a computer for use.

High cost-effectiveness and stable weighing.

Basic functions

• Compatible with all A9 functions ◆ ∑ - Δ high-precision analog-to-digital conversion, capable of processing signals within the range of -16 to 18mV
  

• Replacing the meter does not require recalibration, with high accuracy and good consistency
  

• The DC interface has anti reverse connection and anti short circuit protection
  

• Strong anti-interference ability, suitable for a wide range of environments ◆ AC/DC dual-use, standard battery
  

• 7-digit 0.8-inch LED display, 3-speed battery level indicator
  

• The zero tracking range and zero setting (power on/manual) range can be set separately
  

• Equipped with two-point linear correction function and two compensation calibration methods
  

• Large storage capacity, capable of storing 1001 sets of weighing records, 1000 sets of vehicle numbers and tare weights, and 201 item numbers
  

• Can print weighing forms such as horizontal and vertical links, and can print various statistical reports
  

• Equipped with RS232 communication port (optional RS422/RS485), equipped with current loop large screen communication port, equipped with standard parallel printing port, and supports specified models of thermal micro printers
  

• A9+P built-in needle micro needle
