○
Approved for 10,000divisions
○
Up to 28 measurements per second
○
Excitation for up to 10 strain gauge load cells,
1100Ω each or 4 strain gauge load cells, 350Ω
(minimum input impedance 35Ohm)
The LD5208 is our proposal for
simple and accurate weighing.
The indicator features large crystal
liquid display, compact ergonomic
enclosure for table top or wall mount
use, and battery operation to allow the
use in portable scales or remote
locations.
User friendly, simple and fast in
operation, fully configurable and
easily adapted to your needs, this
indicator is a cost-effective and
reliable solution for a variety of
weighing applications.

SCALE CALIBRATION AND FUNCTIONS
CALIBRATION
Digital calibration (dead load and span) and scale parametrization via keyboard dialogue menu .
The weight display can be set to any capacity and resolution with 5 digits (subject to application
and regulations).
Electronic calibration can be also performed via the m V/V output values of load cells.
WEIGHING FUNCTIONS
Automatic zero tracking, no-motion detection, auto-zero on power-up, zero,
tare (max tare effect = -Max), multiple test functions
FULL SCALE RANGE
The two most significant decades of the digital display are programmable from 1 up to 99 for the
full scale range. Single or dual interval, auto-switching between the different display steps.
MEMORIES
Serial EEPROM for the storage of calibration data
