PM 5414 V INSTALLATION AND SAFETY INSTRUCTIONS
1 - 3
Turn the selector to select the appropirate voltage range. If necessary, insert the specified fuse
(T0.315A or T0.63A according to IEC127 or T0.375A or T0.75A according to CSA/UL198G) that
matches the line voltage setting into the fuse holder.
1.2
OPERATING POSITION OF THE INSTRUMENT
The instrument can be operated on a horizontai surface in a flat position or with the tiiting feet
extended. Ensure that the ventilation hoies are free of obstruction. Do not position the instrument in
direct sun light or on any surface that produces or radiates heat.
1.3
RADIO INTERFERENCE SUPPRESSION
Radio interference of the instrument is suppressed and checked carefuiiy. If radio frequency interfer
ences occur in connection with other deficient suppressed instruments, further suppression actions
may be required.
1.4
ISOLATION TRANSFORMER
Because most MTV and CTV receivers are constructed with the chassis potentiaily ”iive”, it is sensibie
precaution to power the receiver under test via a suitabie isoiating transformer.
This permits direct connection of the teievision chassis to the earth terminais of any test instrument
thus providing a common signai path and reducing the risk of eiectric shock.
