4 Preparation

4.1 Power supply

An internal LiPo battery serves as the power supply. With a fully charged battery, a runtime of approx. 8 ... 10 hours is possible, depending on the display brightness. The battery is charged via the USB port at the bottom of the meter and appropriate USB chargers can be used. The charging process can be shortened by switching off the meter during the charging process.

The current battery charge level is displayed in the status bar at the top right. As soon as the battery charge level is no longer sufficient for proper operation of the instrument, it switches off automatically and the screen shown below is displayed.

Simple red battery icon on black background (no text or symbols)

Fig. 1 Automatic Power Off

4.2 Start-up

4.2.1 Switch on

The meter is switched on by holding down the on/off key for approx. 5 seconds. When the meter is switched on, the start screen with the PCE logo appears for approx. 1 second and then the device switches to the measurement screen.

4.2.2 Switch off

To switch off the meter, press and hold the on/off key for approx. 3 seconds. A dialogue appears on the screen with a countdown that announces that the meter is to be switched off.

4.2.3 Sensor connection (for force gauges with external measuring cell)

The load cell is screwed to the meter by means of the test cable. Connect the test cable to the meter via the plug connection and then secure it with the knurled nut.

4.2.4 Sensor disconnection

The load cell and the meter are disconnected by unlocking the knurled nut and then removing the plug of the test cable from the meter. Then loosen the screw connection between the load cell and the test cable.

7 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.
