IntroductionRanger RC
Scales with a built-in battery can work independently from the mains for approxi­mately 30 hours in normal operation. A prerequisite for this is that the background lighting is switched off and that no peripheral devices are connected.
The device automatically switches to battery operation as soon as the mains supply is
interrupted. When the mains supply is restored, the device automatically switches
back to mains operation.
The

rged (min. 4 hours). The charging period is extended if work is continued during
cha
rging. The battery is protected against overcharging.

e The battery’s charging capacity can be reduced under continuous mains operation.

To maintain the charging capacity, after a maximum of 4 weeks discharge the bat-

2.2 Zeroing / Zero point correction

Zeroing corrects the influence of slight changes on the load plate.
Manual 1. Unload scale.
2. Press ZERO.
The zero display appears.
Automatic In the case of scales that cannot be certified, the automatic zero point correction can
be deactivated in the menu or the amount can be changed.
As standard, the zero point of the scale is automatically corrected when the scale is unloaded.

2.3 Simple weighing

1. Place weighing sample on scale.
2. Wait until the stability monitor goes out.

3. Read weighing result.

2.4 Weighing with tare

2.4.1 Taring

Place the empty container on the scale and press TARE.
The zero display and the symbol NET appear.
The tare weight remains saved until it is cleared.

2.4.2 Clearing the tare

Unload scale and press TARE.
The symbol NET goes out, the zero display appears.
If A.CL-tr is activated in the menu, the tare weight is automatically cleared as soon as the scale is unloaded.
