PART.
Remove the screw irom one end, and replace with the
collar screw, Screw the body spring onto the long part
of the collar screw. slip the emulator sleeve over the
body spring, and slip this assembly into the probe body
with the resistor he do the tip.
Assemble the cable as shown, bysoldering the test lead
to the proper lug on the phone plug. Then replace the
bakelite cap on the phone plug. New solder the test lead
to the eyelet in the connector.
Screw the test lead assembly to the probe body, thus
compressing the body spring, and insuring proper con-
tact between resistor and tip, and between spring and
test lead assembly.
This test probe, when used with a standard 11 megohm
input resistancevTvt/l, will imrease the voltage ranges
I?! a motor at 100.
connect the probe to the VTVM in place ol the regular
DC test probe.

CAUTION: HIGH VOLTAGES ARE Ex-
TREMELY DANGEROUS. NEVER MEA-
SURE DC VOLTAGES IN EXCESS OF

This probe is designed to permit high vol-
tage measurements to be made as sately as
possible.
ALWAYS MAKE SURE THAT THE GROUND
CLIP IS CONNECTED BETWEEN THE
CHASSIS OF THE UNIT UNDER TEST AND
THE VTVM, AND THAT THE PROBE IS
CONNECTED To THE VTVM.
wherever possible, contact the high-voluge
by hooking the tip spring to the terminal un-
der test. This should be done with the power
turned 01f. Then without touching the probe,
turn power on, lake the reading, turn the
power 0E, ecreiuily discharge any high vol-
tage condenserswhleh may be in meoireuit,
and remove the probe (rpm the circuit.
While the conductors inside the handle and
the test lead assembly never carry mare
