SECTION 1 INTRODUCTIONS
1.1 Introduction
The indicator provides an accurate, fast and versatile series of general purpose weighing
indicator with counting, check-weighing, animal weighing functions and preset tare.
1.2 Specification
1.3 Installation
The weighing indicator should be sited in a location accuracy would not be degraded.
Avoid extremes of temperature.
Avoid unstable power sources. Do not use near large users of electricity such as welding
equipment or large motors.
Verify the voltage showing on the label matches the voltage in your area.

SECTION 2 KEY DESCRIPTIONS
SOFT POWER ON/OFF Key

2
Power on/off the indicator.
ZERO Key
1) When self-checking, Press ZERO Key to enter parameter setting;
2) Set the zero point for all-subsequent weighing;
3) Move the cursor to change the digit when setting parameters or other functions.
TARE Key
1) When self-checking, Press TARE Key to enter fast calibration;
2) Tare the scale. Store the current weight in memory as a tare value, subtract the tare
value from the weight and shows the net weight. Entering a value using the keypad will
store that value as the tare value;
3) Cycle through the functions or increase the active digit when setting value for
parameters or other functions.
MOD/ ESC Key
1) Enter / Cancel the counting mode from weighing mode when “F3 KEY”=1;
2) Accumulate and print when “F3 KEY”=2;
3) “Hold” Function keep and cancel when “F3 KEY”=3;
4) Enter pre-tare value when “F3 KEY”=4;
5) Parameter setting for animal weighing when “F3 KEY”=5;
6) Cancel or quit from the operations.
FUN Key
1) Select or enter the function and save the setting values of parameters;
2) View unit weight, counts and total weight when counting mode (“F3 KEY”=1);
3) View nos. of accumulated weight and total weight when “F3 KEY”=2;
4) Enter/Cancel animal weighing function when “F3 KEY”=5;
UNIT Key
1) When self-checking, press UNIT Key to set unit conversion coefficient.
2) Unit conversion when weighing.
