PROBE TERMINATIONS
a.
General: The probe terminations are factory sealed and their disassembly
is not recommended. If damaged, replace.
If a termination is suspected of being f a u l t y , first check that the center
b.
pin is making firm contact with the diode cartridge. An increase of mechanical re-
s i s t a n c e should be noted as the termination is within 1/16" of its final tightened
position.
Type 50-ohm termination adapter: Check the resistance value of the film re-
c.
sistor using the DC multimeter set to ohms. It should measure 50-ohm (49-ohm to
5 1 - o h m ) . If out of tolerance, replace.
Probe and diode cartridge assembly.
SWITCH CLEANING
A periodic lubrication and cleaning of the switch contact points is necessary for
prolonged accurate readings. They may be cleaned if necessary with the tip of a
soft cleaning cloth and a minimum of solvent without the disassembly of the
switch.
WARNING
Compressed air shall not be used for cleaning purposes except where
reduced to less than 29 pounds per square inch (psi) and then only
with effective chip guarding and personnel protective equipment. Do
not use compressed air to dry parts when TRICHLOROTRIFLUOROETHANE has
been used. Compressed air is dangerous and can cause serious bodily
harm if protective means or methods are not observed.
