Operation
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.
Safety: Meets the safety requirements for double
insulation to IEC1010-2-031 (1995), EN61010-2-
031 (1995), IEC1010-1 (1995), EN61010-1
(1995) Category III*, 300V phase to earth. The
probe is fitted with an internal, non-replaceable
fuse, to protect the user should the probe be
used accidentally in conjunction with a test lead
in the low terminal.
* Relates to transient overvoltage likely to be
found in fixed installation wiring.
Do not use the probe if any part of it is
damaged.
