Problems with Instrument Activation
If TTI-22 cannot be switched on or immediately switches itself off again after activation, check the following:
1.
If you operate TTI-22 with batteries/rechargeables, check their charge condition.
2.
If you operate TTI-22 with a power adapter, check whether the power adapter is correctly plugged
in.
3.
If the instrument immediately switches itself off despite functional power supply, check the sensors:
•
Disconnect the sensors from TTI-22.
•
Switch on the instrument.
If it is switched on without problems, the error is caused by a defect of the sensor or sensor cable.
•
Repair the sensors or sensor cables or exchange them.
