2.7.3 Charging procedure

........................................................................................................................................

Before the D190 remission densitometer is used for the first time, it must be charged with the

supplied charger. A fully charged battery allows for approx. 4000 measurements.

........................................................................................................................................

Procedure:

• Connect the charger to the power supply via the power cable.

• Connect the charger to the D190 remission densitometer via the charger cable.

• Charge the battery for approx. 3 hours.

• Remove the charger cable and disconnect the charger from the power supply.

........................................................................................................................................

The rapid charge of the battery results in a noticeable temperature increase in the housing.

This temperature increase is not of importance and will disappear when the battery is fully

charged.

2.8 Data protection

The data storage is backed up by a buffer battery with a service life of about 10 years. This prevents

a loss of data even if the rechargeable battery is not installed.
