CALIBRATION

The ATX-R Series is equipped with a perfect self calibration (PSC) function which carries out

fully automated span calibration when temperature changes are detected in order to allow for

accurate measurements.

PSC is carried out automatically in mass measurement mode under any of the following

conditions. The calibration weight symbol will blink approximately 2 minutes before PSC

begins as a notication.

(1) When there is a change in the surrounding temperature.

(2) When about four hours has passed since the previous calibration.

(3) If the balance switches to mass measurement mode after conditions (1) or (2) above are fullled in the

standby or menu display states.

� The symbol will blink when any of

conditions (1) through (3) above are fullled.

Once 2 minutes elapses after the symbol

begins blinking, different operations will be

carried out as detailed below depending on if there is any load on the pan or not.



Case1) There is no load on the pan.

"PSC.RUN" is displayed and automatic span

adjustment is executed.

It returns to the weighing mode when automatic

span adjustment ends.

To continue weighing when "PSC.RUN" is displayed, press to stop span calibration.

The balance will return to mass display without completing span calibration and the symbol will

blink.



Case 2) There is some load on the pan.

(a) In the case of a veried balance

The symbol will continue to blink until there is nothing on the pan. Span calibration will

begin when the sample is removed from the pan.

(b) Except for a veried balance

The symbol and mass display will both blink. After 2 minutes have passed since the

mass display begins blinking, "PLS.CAL" will be displayed, so remove the sample from the

pan so that there is nothing on the pan. Span calibration will then begin.

The symbol will continue to blink even if there is nothing on the pan when using the application

function mode. Span calibration will begin after switching to mass measurement mode.
