2.6 Testing balance
The "Test" function, which you can call up by pressing and holding the key, allows you to check the accuracy of your PR/
SR balance at any time. The deviation from the target value determined by the balance is displayed and recorded in conformance
with GLP. You have a choice of two methods here:
Checking with an internal (built-in) weight; here, the test point is fixed, or
Checking with an external weight whose value can be freely entered within the load range of the balance.
Procedure for testing the balance with the internal weight
Requirement
The setting of the test function under "CAL" in the menu corresponds to the factory
setting (see section 6.3).
Remove any load from the weighing pan.
Initiate test with pressing and holding the key and by pressing the
SmartBar under the word "Test".
During the test, "BALANCE TEST" appears in the bottom line of the display.
When the test is complete, the difference between the actual value and the target
value appears for a few seconds in the top line of the display marked by "" and
"D". The balance then returns automatically to the weighing mode. A tare value
displayed before the test reappears in the display.
If a printer is attached, e.g. LC-P43 from METTLER TOLEDO, the test result is
automatically printed out.
You can terminate the test at any time by pressing the N key.
The deviation determined by the balance depends on the ambient conditions!
