Please check that your Staht proof load tester is charged. Use the USB-C port and charging cable to charge the unit. You can plug it into the mains, a power bank, or a USB car charger. If after a full charge it does not switch on, then please contact the Staht Technical Support team.
You can manually switch off the proof tester by pressing and holding the <GREEN> button for 2 seconds. If the load on the screen is <0.3kN, your Staht tester will automatically shut off after 10 minutes of inactivity. If the load on the screen is >0.3kN, then your Staht proof load tester will remain on, as load is being applied by the unit.
Please ensure that the correct USB-C adaptor lead is being used, and it is in good condition. Please ensure that it is correctly located in the charging port, and that it is receiving power from the other end via the mains or a charged power bank.
Approximately 8 hours with constant use with a Bluetooth® wireless connection from a full charge.
The proof load tester is powered by a rechargeable Li-ion battery. Under international shipping regulations, new items are not shipped fully charged. Fully charge the battery prior to first use. It takes 2 hours to fully charge using UK mains charging.
