Label Name Function
E L2 (Neutral)
Switch Permits making leakage current measurements
under the OPEN neutral (L2) condition as
required by UL and IEC.
F Lift Ground /
M.A.P. Switch A dual function switch. The LIFT GROUND
position will open ground to the device for
leakage current measurements. The MAP test
position will energize the selected patient lead at
mains voltage, current limited, to measure the
isolation current when the function switch is in
the M.A.P. position. With the function switch in
the EXTERNAL position, the isolation test
voltage is supplied to the EXTERNAL connector
for measuring the isolation current of a probe or
transducer.
G Function Switch Provides direct one-step selection of the
measurement to be made. The functions are:
Mains voltage, instrument current, grounding
(earth) resistance, earth and leakage currents
and the patient lead currents. These include lead
leakage, auxiliary current and mains on applied
parts (M.A.P.) for isolation (sink) current. An
external position is provided to measure leakage
current between two points, or isolation current
of probes and transducers, independent of their
instruments.
H Lead Switch Directs the selected measurement to the desired
patient lead. When testing a 10 lead device, a
second pass is required for the C leads. The
setting to the far right is the ALL lead position.
I Meter (Display) A large, ½ inch, high contrast 3½-digit display of
the measured parameter. This can display 1999
with decimal points added where required
J Universal
Patient Leads Provide means for the connection of the patient
leads for leakage current measurement.
