INDEX OF CONTENTS
INDEX OF CONTENTS
1. INTRODUCTION
5144, 5145, 5183 Series analytical balances work on electromagnetic force compensation technology
and microprocessor, which allows high speed stabilization and high reliability. They can be widely used
in industry, agriculture, commerce, schools, scientific research and other institutions.
Safety precautions
Avoid direct sunlight
Avoid vibrations
Avoid strong drafts
Avoid temperature fluctuations
Verify that the AC/DC adapter input voltage matches the local AC power supply
Sufficient spacing for balances: >15cm all around the instrument

2. PREPARATION
Put the balance on the stable desk, the desk can not be moved.
Adjust the two feet on the bottom, until the bubble is centered in the circle, then place the balance
pan.
Plug in the AC/DC adapter and connect the control panel with the balance.

Conexión y encendido
Press the ON/OFF button. Balance enters the weighing interface.
When the operating temperature changed, put the balance in the new place for 2 hours in the state
of “power on”, to make the balance comply with the new temperature. Recommended temperature
between 15 and 25 ºC.
Attention: lf the number on display is not stable in first boot, this occurred by operating temperature,
you can press “TARE” botton repeatedly and lay aside for 30 minutes.
In order to get accurate weighing result, balance should be calibrated in below usage scenarios.
1. Before first use
2. Balance power off for long time
3. After changing the operating environment
4. Perform regularly in weighing procedure
Chose the calibration method (follow the sequence)
3. CALIBRATION
Enter the calibration mode
External calibration mode
Internal calibration weight value setting mode (balance
with internal calibration only)
Internal calibration mode (balance with internal calibra-
tion only)
Auto-calibration every 30 minutes (balance with inter-
nal calibration only)
Auto-calibration every 1 hour (balance with internal ca-
libration only)
Auto-calibration every 3 hours (balance with internal
calibration only)
