Solder LINK L1
Solder Link L1 is used to select to power supply mode of the
EM32-1B.
With L1 in the default configuration, the module operates from a
3.5 to 6.5Vd.c. supply, and measurements can be made with
respect to power supply 0V.
When L1 is re-configured, the module operates from a 7.5 to
14.0Vd.c supply. The voltage being measured must then be
floating with respect to the meter's power supply.
