2. To make a UV light reading please follow these directions and refer to the photo above.
a) Place sensor (A) inside PCR Workstation and meter (B) outside Workstation where it can
be read easily.
b) Insert PCR Workstation door into place so that it rests gently on top of the sensor chord.
c) Close glass fascia of PCR Workstation
d) Turn on UV light and read meter.
e) Turn OFF UV light BEFORE removing sensor.
f) Multiply meter reading by 100µW/cm 2
3. Compare UV dosage to table 3.2. If any value is less than listed for your particular PCR Workstation, you
have 2 choices:
a) Replace the old bulb.
b) Extend the time of UV exposure. For instance, if the meter reading is 350µW/cm 2
(instead of 400 for a new bulb in the P-048-202), you can achieve the required
dosage by leaving the UV light on longer.
c) Please refer to the references #1 and #3 to determine exposure time.
4.3 Maintenance
The following inspection and maintenance procedures will help maintain the safety and reliable performance
of the PCR Workstation ® . Replacement parts can be ordered by calling 1-858-755-4959 or by contacting
your local distributor.
• Power cords should be inspected regularly. If they become loose or do not feel friction tight replace
the plugs or power cords.
• Should power cord assemblies (connectors, wire or shrouds) show any signs of wear or damage
(e.g. cracks, nicks, abrasions, or melted insulation), replace them immediately.
Directions for using UV Light sensor and meter in
PCR Workstation to determine UV dosage
CAUTION: Always make sure that glass fascia and PCR door are in closed position BEFORE turning on UV light.
1) Place sensor (A) inside PCR Workstation and meter (B) outside Workstation where it can be read easily
2) Insert PCR Workstation Door into place so that it rest gently on top of sensor chord
3) Close glass fascia of PCR Workstation
4) Turn on UV light
5) Read Meter
6) Turn off UV light BEFORE removing sensor
7) Multiply meter reading x 100µwatts/cm
2
8) During heavy usage readings should be taken weekly. As bulbs age, longer exposure may be necessary to
achieve desired dosage.
