Communication – data transfer
Data transfer between the REVEXmax and the PC is completely controlled by the
PC software and it cannot be controlled directly from the measuring device. To
transfer data, prepare the REVEXmax as follows:
Connect the REVEXmax to a PC using a USB cable plugged into connector
11 (drivers must be installed on the PC for the proper use of USB communi-
cation).
If the REVEXmax is in the mode of working with databases, shut it down and
set the device to measuring mode.
Before transferring data from a PC to the REVEXmax, memory will be erased.
How long it takes to erasing entries depends on the memory usage. It can take
up to 2 minutes when all memory locations are occupied. Attention: data
unsaved to the PC will be lost forever!
Do not operate with the instrument during data transfer.
An informative window is displayed during data transfer.

Warning messages
PE error
A fault occurred in the PE circuit. The cause may be:
the PE conductor circuit is not sufficiently grounded (high impedance fault
loop or IT system)
voltage on the protective wire
All device functions are blocked. If it is the IT system, the user must confirm this
condition (see Figure 5). The resistance of the PE conductor, substitute leakage
current and insulation resistance can be only measured in IT systems. In other
cases, we cannot continue measuring (see Figure 6).
The test of the PE circuit is performed only once, immediately after
connection to the mains.
