The key points of using Sartorius electronic balance

The key points of Sartorius electronic balance The electronic balance is a common instrument and equipment in daily life.
It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration device and overload protection devices
.

There are various brands of electronic balances, and Sartorius is one of them.
The following editor will introduce the key points of its use.
Let’s take a look.
Notes 1.
Electronic balances actually measure the earth’s The gravitational force of the object on the disk is the gravitational instrument.
Because the diameter and latitude of the earth are different, the gravitational acceleration (g ~ 9.
8m2/s) in different places is also different, so the electronic balance must be calibrated after transportation or handling.
use, and use matching weights
.

2.
The key components of Sartorius electronic balances: gravity electromagnetic sensor reeds (usually 6 to 8 pieces), thin and thin, easily damaged, the analytical balance has high precision, and the thickness of its gravity sensor reeds is thicker.
It is thin, so users should pay more attention and protect it during operation, so as not to overload the balance and easily damage the sensor
.

Note: The operator must not press the weighing pan or drop the balance by hand during use, which will damage the analytical balance or cause the performance of the gravity sensor to change.
In addition, when weighing, especially for heavier objects, do not pass for more than 30 seconds.
Remove the pan and tray when moving or transporting the electronic balance

3.
The calibration mechanism of Sartorius analytical balance is usually divided into three types: (1) Fully automatic calibration: it contains standard weights and motor servo mechanism, and the calibration can be completed within tens of seconds by pressing a function key.
The new Sartorius electronic balances with an accuracy of more than 1/10,000 gram adopt fully automatic calibration; (2) Semi-automatic calibration: standard weights are built in but there is no servo mechanism.
After entering the calibration procedure, you need to manually load or unload the calibration weights (3) Manual calibration: There is no standard weight and servo mechanism inside the electronic balance.
It needs to manually enter the calibration program and add standard weights for calibration.
Usually, electronic balances with lower accuracy are manually calibrated
