Hand-held Analyzer 2250 Light – User Manual

9.3.3 Battery Pack and Recalibration of Battery Charge Indicator

The software keeps the capacity of the battery pack updated. Over time the total capacity of the

battery pack decreases. If you find that the ‘Time Remaining’ estimate (tap on the battery icon

to get this information) does not match the real time remaining (for example, the

instrument switches off automatically because of lack of power while the Time Remaining

estimate indicates at least ½ hour), then you should manually re-calibrate the capacity of the

battery pack. This is done using the following method:

• Drain all the power from the battery:

– Switch the instrument on

– Disconnect external power

– Disconnect the instrument from the PC

–In the Preferences menu, under Power Settings, set Standby After to Never

– You may want to set Backlight On to Always (in the same menu) and select the

maximum level of display backlight in order to drain the battery faster (use the

Backlight icon at the bottom of the screen)

– Leave the instrument until the battery voltage becomes so low that the analyzer

switches itself off

• Charge the battery fully (at least 10 hours):

– Connect the Mains Power Supply ZG-0426 (or ZG-0429) to the analyzer

– Switch the instrument on (and leave it on) and remember to reset the Standby After

and Backlight On to your preferred settings

Tap the battery icon and a pop-up appears, giving details of the battery condition. This

will indicate Calibrating Battery initially. Let the battery charge until the battery charge

indicator just below the power socket starts flashing green (hardware versions 1–3) or changes

from red to green (hardware version 4) and the Calibrating Battery indication has disappeared

from the pop-up window.

9.3.4 Touch Screen

If tapping with the stylus on the screen seems to be getting more inaccurate, you can adjust the

touch sensitive screen, as follows:

• In the Preferences menu, under Display Settings activate the link Adjust Touch Screen.

This displays a full screen with guidance on how to tap on a cross five times at different

places on the screen. The adjustment procedure ends with saving the values or cancelling

the adjustment
