`lamp:
`
`Always operate the light source in its upright
`position.
`
`If you are going to use the light source more
`than once during the day, leave it on. Lamp
`wear results more from turning the light source
`on and off than from steady operation.

`
`Introduction
`
`The PASCO scientific Model OS-9286A Mercury Vapor
`Light Source provides approximately 3,000 lumens of
`light in the mercury spectrum. The 100 watt light source
`comes ready to use, with a built-in power supply so the
`unit can be powered from a standard 115 VAC, 60 Hz
`outlet (OS-9286A-220 is powered from a 220 VAC, 50
`Hz outlet). Cooling fins and air vents on the sturdy alu-
`minum case ensure cool, safe operation. In addition, rails
`on the front and rear of the case can be used for mounting
`standard 2-inch by 2-inch filters, so that monochromatic
`light can be obtained.

`
`Wavelength of the Mercury Spectral Lines
`
`All values except wavelength for yellow line are
`from Handbook of Chemistry and Physics, 46th ed.
`The wavelength of the yellow was determined ex-
`perimentally using a 600 line/mm grating.
`NOTE: The yellow line is actually a doublet with
`(cid:5)
`wavelengths of 578 and 580nm.
`
`To Operate the Light Source:
`Simply plug it into a standard, grounded, 115 VAC (or
`220VAC) outlet; then flip the switch on the front of the
`light source to ON.
`
`CAUTION: The outer glass tube of the mercury
`(cid:5)
`vapor lamp blocks harmful ultraviolet radiation
`produced by the lamp. If the outer tube is cracked
`or broken, this radiation can cause severe skin
`burn and produce eye inflammation. Regularly
`inspect the outer tube for cracks, especially if the
`light source has received a significant jolt. If the
`glass bulb is broken, immediately turn lamp off and
`remove it to avoid possible injury. Replace Bulb
`prior to next use.
`
`CAUTION
`RISK OF ELECTRIC SHOCK
`DO NOT OPEN
`
`CAUTION:
`TO PREVENT THE RISK OF ELECTRIC SHOCK, DO
`NOT REMOVE COVER ON UNIT. NO USER SERVICE-
`ABLE PARTS INSIDE. REFER SERVICING TO QUALI-
`FIED SERVICE PERSONNEL.
`
`The lightning flash with arrowhead, within
`an equilateral triangle, is intended to alert
`the user of the presence of uninsulated
`“dangerous voltage” within the product’s
`enclosure that may be of sufficient magni-
`tude to constitute a risk of electric shock to
`persons.
`
`The exclamation point within an equi-
`lateral triangle is intended to alert the
`user of the presence of important oper-
`ating and maintenance (servicing) in-
`structions in the literature accompany-
`ing the appliance.
`
`Maintenance
`The light source lamp can be expected to provide
`24,000+ hours of trouble free operation. However, if the
`light at any time fails to come on, first check the fuse on
`the front of the light source case. If the fuse is not
`blown, you may need to replace the lamp. In rare cases,
`the problem may be with the ballast. However, ballast
`replacement should be performed only by experienced
`personnel. If the fuse is intact and replacing the bulb
`does not restore operation, we recommend you return the
`unit to PASCO scientific for repair.
`
`CAUTION—HIGH VOLTAGE: Do not open the
`(cid:5)
`light source with the unit plugged in.

`
`Unplug the light source. Allow 10 to 15 minutes for
`the lamp to cool.
`Unscrew the eight screws that attach the top plate of
`the light source and remove the top plate.
`Using a glove or several folds of thick cloth to protect
`your hand, unscrew the lamp. Discard it as you would
`any broken glass.

`
`Equipment Return
`
`PASCO scientific warrants this product to be free from
`defects in materials and workmanship for a period of one
`year from the date of shipment to the customer. PASCO
`will repair or replace, at its option, any part of the product
`which is deemed to be defective in material or workman-
`ship. This warranty does not cover damage to the product
`caused by abuse or improper use. Determination of
`whether a product failure is the result of a manufacturing
`defect or improper use by the customer shall be made
`solely by PASCO scientific. Responsibility for the return
`of equipment for warranty repair belongs to the customer.
`Equipment must be properly packed to prevent damage
`and shipped postage or freight prepaid. (Damage caused
