Maintenance And Calibration - Mettler Toledo PE200 Mode D'emploi

CARE AND MAINTENANCE: Upkeep and calibration
Your METTLER TOLEDO PE balance requires very little maintenance, but it should be cleaned and calibrated at regular intervals.
Before checking the calibration, the balance must have been switched on for at least 30 minutes (warm-up time).
Cleaning
Weighing pan, in-use cover and, if necessary, the
balance housing should be cleaned whenever the
need arises.
As much as possible, avoid using strong solvents.

Calibration
If your balance is to deliver accurate weighing results,
it must be properly calibrated.
Check the calibration of your balance at regular
intervals; in case of constant operation, at least once
a month.
The test weight to be used with your balance model
is listed under "ACCESSORIES, Optional equipment".
Rechecking the calibration
– Press single control bar (15):
The display indicates zero.
– Place test weight on pan and read the result.
If the result now displayed by the balance corre-
sponds to the weight indicated on the test weight
down to the last decimal, your balance is ready for
use. If not, it has to be calibrated.
For instructions on how to do it, see "OPERATION:
How to calibrate the balance" (page 7).
