Using the MEGGER SP1 Switched Probe
Operation
The MEGGER SP1 is an accessory for designated
MEGGER installation test instruments. When fitted
in the specially designed connector, in place of the
existing 'Low' lead, the SP1 acts as a remote test
button to operate the instrument and as a 'Low'
probe. This simplifies instrument control and two-
handed probing. The SP1 is suitable for use with
MEGGER insulation test instruments up to 1kV
output test voltage.
