1. The device has been switched on, but the display remains dark
Check the power supply line to the device
Check that the mains voltage selector switch is in the correct position.
Check whether the device fuse is still intact.
Switch the device back on after performing the above actions.
If the problem still exists, contact PeakTech Service.
2. Initial values behave in an unusual way:
Check whether the voltage has been set to 0V. If so, change the voltage value.
Check whether the current has been set to 0A. If so, change the current value.
If the timer mode has been selected, check whether one of the sequence steps is set to 0A or 0V. Change
this value if necessary.
If the problem still exists, contact PeakTech Service.
3. The USB storage device is not recognized correctly:
Check the storage medium for function with another device, e.g. a PC.
External USB hard drives are not supported, only flash memory can be used.
Restart the device and insert the USB storage medium again.
