PC Software
The PC software can create, download and store instrument configurations & profiles. If the
recorder feature is fitted, its recordings can be downloaded and analysed via the software.
In addition, changes can be made to the instrument operation by adding extra screens,
amending the contact details, alarm status labels or to the functions and labels of the
LED’s.
The software can download a new language file, change the start- up “splash screen” or
configure the “Supervisor Mode” screens. An on-screen simulation of the instrument can be
setup and tested on a configurable load simulator.
Refer to the PC software and use sections of this manual for full details.
Also refer to: LEDs and Supervisor Mode.
