4 QUICK START GUIDE
4.1 SETTINGLAMP PARAMETERS
1. Press the horizontal menu button under the Lamp Mode icon. If Power Mode is desired, press the
horizontal menu button under the Lamp Mode indicatoruntil Power appears under Lamp Mode. If
Current Mode is desired, pressthis menu buttonuntil Current appears under lamp mode.
2. Upon choosing a lamp mode the operating power/current (Pset/Iset) and maximum operating
power/current (Pmax/Imax) will appear on the vertical menu. Press thevertical menu button next to
Pset/Iset and use the knob toset this parameterwhen a red bullet appears next to the current value.
Then, set Pmax/Imax. This is typically setto10% above the rated power/current for the lamp being
used.
Be aware that the Imax setting will determine the maximum current the power supply will supply to
the lamp, even if the lamp is being operated in Power mode. If the lamp is being operated in Power
mode and not reaching the Pset as directed by the user, turn off the lamp. Then, increase Imax while
staying within the lamp’s maximum current specification. Revert back toPower operation mode and
ignitethe lamp.
Please note that Power, Current,and Intensity Modesshare the same Imax setting. Changing
the Imax setting in one mode of operationwill change the Imax setting for the other modesof
operation. Before igniting the lamp, the maximum specifications should be confirmed and
presetby the user to avoiddamageto the lamp.
4.2 TURNING THE LAMP ON/OFF
When the lamp parameters have been set, press the LAMP button on the front panel. The OPS-Q
Series PowerSupplies have a Soft Start feature. These power supplies gradually apply poweror
current on lamp start-up and gradually reduce power or current on lamp shut-down. This prevents
catastrophicdamage tothe filament from in-rush current on lamp start, and minimizesstress to the
lamp. The reduction in thermal shock tocalibrated lamps ensures longer validity of the calibration.
As a result, a user may notice the QTH lamp/IRemitterdoes not instantly ignite or power off when
directed by the user/powersupply.

4.3 LIGHT INTENSITYCONTROL
1. The flux set point must be set first. There are two ways toset the flux set point:
A. AutoSet method:
i. Use “Current” or “Power” mode to turn ignitethe lamp first
ii. Press the horizontal menu button under “Display”and select “Lamp Intensity”
using the externalknob.
iii. Press the right mosthorizontalmenu key under Setup until the vertical menu with
CoolTemp, Idle, and Autosetappears.
iv. Press the “AutoSet” button, the systemwill automatically adjustthe gain of the
flux amplifierand set the flux set point to be 90%ofcurrent flux reading
v. Turn off lamp
B. Manual method:
i. Use “Current” or “Power” mode to turn ignitethe lamp first.
ii. Press the horizontal menu button under “Display”and select “Lamp
Intensity”using the external knob.
iii. Record this value. This value is to be used as the “Flux Set” set point.
iii. If the recorded value shows value of 2.5uA, 25uA or 250uA or 2500uA,
this indicates that the flux reading has overflowed with existing gain of
flux amplifier. If this occurs, the Autoset Method described above should
be used.
iv. Turn off the lamp.
v. Press the horizontal menu key under “Lamp Mode”and continue this
button until Intensityappears.
vi. When Intensity appears, press the vertical menu button next toFlux Set.
Use the knob to change this value to10% greaterthan the Flux Set point
just recorded.
Users who used the Manual Method describedabove to establish a Flux Set point can skip Steps
2 and 3 and proceed withpressingthe LAMP button to operate the lamp.
2. To change the lamp control mode, use the horizontal menu key under “Lamp Mode”and
press this button until Intensity appears.
3. Once Intensity modeis selected, press thevertical menukey next to Flux Set and use the
knob to adjust this value. Press the LAMP button toignitethe LAMP.

4. When in “Intensity”mode, if the signal output and/or TE cooler cables connecting the power
supply to the 71582 light intensity control kit detectorare not connected properly, “Cooler
Not Ready”may appear on the message bar of the LCD screen. If this appears, inspectthe
cables to confirm secure connections.
5 OPERATING MODES
5.1 POWERMODE
In power mode, the lamp is operated at a constant powersetting. As the voltage cannot be changed, the
current is raised or lowered tomaintain the powerat the same level. As the lamp ages, the radiant output
decreases. As an IRemitterages, its resistancemaydouble. However, the lamp life is prolonged.
5.2 CURRENT MODE
In current mode, the lamp is operated at a constant current setting. As the voltage cannot be changed,
the power is raised or lowered tomaintain the current at the same level. As the lamp ages, the power is
increased. This results in greater optical output which to some extent may help compensate for a
darkeninglamp envelope. However, the lamp life is reduced due tothe increase in power.
5.3 INTENSITYMODE
Light intensity mode allows the user to increase or decrease the output intensity ofthe lamp from a Flux
Set point. In order operate the lamp in Intensity Mode, the LIK-LMP Light Intensity Controller Kit (sold
separately) from Oriel Instruments is required. The LIK-LMP light intensity kit includes a TE cooled
detector, and all the necessary adapters and cables for mechanical and electrical compatibilitywith the
lamp housing (both 60000 Q Series and 45-1000 W Oriel Research Lamp Housings adapters included)
and OPS model power supply. While operating in Intensity Mode, varying the Flux Set parameterallows
the user to increase/decrease the output power intensity of the lamp during operation. If a calibrated
photodiode or other current output detector was used to determine the desired output intensity of the
lamp while the Flux Set was being adjusted, the flux (labeled as Output Intensity) displayed on the LCD
screen of the power supply can be adjusted to match the current output of the calibrated detectorby the
use of the Flux Cal Factor. Withthe use of the LIK-LMP, Intensity Mode ensures stable operation ofthe
establishedflux set pointof the lamp over long operationperiods.
5.3.1. Dosed Mode
Dosed mode is a special operating feature of Intensity Mode. When the lamp is in intensity control
mode and a TTL shutter is used, a user can set the Dose for the lamp to output. A Dose consists of a
flux and a time interval. When a user sets a flux set point in intensity mode and switches to dose
mode, a Dose should be specified by the user. The user should also specify the time interval for the
shutter to remain closed in between individual exposures of this Dose, and the amount of cycles
he/she would like this Dosed exposure to repeat for. Time is not directly set by the user, the time
interval the shutter remains open allowing the lamp to directly output light is determined by the power
supply based on the flux set point and the Dose as desired by the user. While operating in Dosed
mode a user can Stop a cycle of exposures, pause the current cycle while the shutteris closed, or
reset the Total Dose the lamp has output thus far as recorded bythe power supply.
