Model 621 User’s Manual INTRODUCTION
Bristol Instruments, Inc. 6
Always use the three-prong AC power cord supplied with this instrument. Failure to
ensure adequate grounding by not using this cord may cause instrument damage.
Do not connect AC power until you have verified the line voltage is properly grounded
and within the specified range (90–260 VAC and 47–63 Hz). Damage to the instrument
could result.
This instrument has autoranging line voltage input. Be sure the supply voltage is within
the specified range.
Maximum safe input is 10 mW of optical power. Laser input power in excess of 10 mW
can result in damage to the instrument.
Use care in handling fiber-optic connectors. Always clean the fiber end prior to insertion
into the instrument’s fiber-optic connector for optimum performance. Failure to do so can
result in damage to the instrument. To prolong instrument service life, it is advantageous
to attach a new fiber-optic patchcord to the instrument and use its other end for the
connect/disconnect procedure.
