5. ROUTINE OPERATIONS AND MINOR MAINTENANCE
The constant should normally not be changed without further investigation, but the mechanism may
be cleaned with a lint-free cloth and isopropyl alcohol The micrometer should normally not require
lubrication, and the only lubricant KIPP & ZONEN uses in the Spectrometer is High Temperature

Standard Lamp and Mercury Lamp
The two internal test lamps (Standard Lamp and Mercury Lamp) have an estimated lifetime of
about two years.
The Standard Lamp can be accessed by removing the plate located behind the Zenith Drive Motor.
Once the two screws are removed, the plate can be detached, bringing with it the lamp socket and
the lamp.
Great care must be taken not to touch the new lamp with bare hands as oil and/or moisture may
change the spectral characteristics of the lamp.
The Mercury Lamp may be changed by loosening the two thumbscrews on the lower part of the
Lamp Assembly.
The Lamp and its socket can then be slid forward (toward the PMT), and the new lamp installed.
Great care must be taken not to touch the new lamp.
When replacing the lamp and socket, observe that there is a small aligning pin at the top of the
assembly.
Backup Battery
The Clock battery on the Main Electronics PCB has an extremely long lifetime under normal
operation (power always on) of the Brewer, and it is unlikely that it will have to be changed for many
years.
In the event that the Battery does require replacement, it can be accessed on the PCB by removing
the seven screws securing the rear PCB protective plate, and sliding the plate up.
The battery is located on the lower left hand corner of the main circuit board.
Prior to removing the battery the power should be turned off, and the small jumper immediately to
the right of the battery should be removed.
The battery can then be slid to the left and taken from its holder and replaced with a 3v Lithium
Battery, KIPP & ZONEN # 75-01-020.
Following replacement, the jumper must be replaced, the panel put back on, and the Brewer given
a cold start.
