The second option has no external VT to CT links, so the meter lid must be removed to
change the links. Figure 6-11 shows the location of the links in this case, just above the
terminal block.

To remove the link connections, remove the four screws and washers from the deeper
set of holes. This disconnects the links. Figure 6-12 shows the meter with the screws
removed.

Config Jumper
The
Config
jumper offers a level of hardware security to the meter – the jumper needs to
be fitted to allow calibration and recovery of lost passwords. The jumper is located
under the meter lid, along the top of the meter on the right side above the LCD (Figure
6-13). A jumper is fitted across the set of pins marked
Config
. The other set of pins
marked
FTest
are for factory use only.
