5.1 The display
Figure 3
5.1.1 Status tokens
The status tokens in the display indicate following:
CV - Voltage regulation active (only if output is „on“)
CC - Current regulation active (only if output is „on“)
Preset V/C - Set value display of voltage/current active
Preset OVP/OCP - Set value display of OVP/OCP active
OT - Overtemperature error
OCP - Overcurrent protection
OVP - Overvoltage protection
Remote - Remote control active (via USB)
Lock - Control panel lock active
5.1.2 Error indication
If an error like overvoltage, overcurrent or overtempera-
ture occurs it is displayed by the text „Error“ and a token
(OT, OCP, OVP) and the output voltage is cut off. The text
remains in the display until the user has acknowledged
the error with the „On/Off“ button, which will also switch
the output off. After an overtemperature error, the output
voltage will return automatically and „Error“ will be cleared,
unless the output has been switched off by the user. Other
errors require the user to switch the output on again, in
order to continue working with the device.
Other display elements are connected to certain operation
modes and are explained in the following sections.
