This section refers to manual operation of KI7400C/7800C Series
Light Source and KI7300C/7700C Series Loss Test Set, Light Source
Section. After instrument turn on, the display shows ‘Source off’. To
turn on the source emitter, press [Source].
The source is scrolled or turned off using [-/+].
The active wavelength is shown on the right hand side of the display
and source power level is at the left hand side. Press [Source], then
[Mod] to display modulation frequency.
To change modulation frequency, press [Source], then [
] and
[KHz] on the hidden keypad. Use [+/-] to scroll available modulation
frequencies: 0.27 KHz, 1 kHz, 2 kHz, then press [Set] to store.
Laser Output Power Adjustment
To adjust laser output power, turn the laser on, then select [
] and
[Level] on the hidden keypad.
Press [-/+] to adjust the level, then [Set] to save. This function does
not operate in Autotest mode and is not available on LED sources.
Visible Laser Operation
(KI7601C instruments only)
Visible laser is a useful low skill fault finding tool and is either PC or
APC connector-specific. This is determined when ordering the
instrument, and can only be changed at the factory.
The visible laser works equally well in single mode and multimode
systems. Although red light is visible at the fiber end up to about
5km, best performance will be achieved over distances of less than
1km.
If the laser light is inserted into a faulty system, the fault point will
glow red visible through 3mm patch lead jackets. Please note this
should be tested before proceeding as some types of patch lead
jackets absorb light. It is also generally possible to locate faulty
connectors in the same way.
To switch on the visible laser, press [POWER] then [SOURCE]. To
turn off the laser, press [-/+].
To improve visibility, the laser is modulated at 2Hz. To change
modulation frequency, press [
] and [KHz] on the hidden keypad.
Use [+/-] to scroll available modulation frequencies: 0.27 KHz, 1 kHz,
2 kHz, then press [Set] to store.
WARNING!
The KI7601C visible laser, classified as Class 2, is eye safe as long
as magnifying devices are not being used.
