1.
The PhD Lite personal, portable gas detector has been designed for the detection of
dangerous atmospheric conditions. An alarm condition indicates the presence of a potentially life-threatening
hazard and should be taken very seriously.
2.
In the event of an alarm condition it is important to follow established procedures. The
safest course of action is to immediately leave the affected area, and to return only after further testing
determines that the area is once again safe for entry. Failure to immediately leave the area may result in serious
injury or death.
3.
Use only Duracell MN1500 or Ultra MX1500, Eveready Energizer E91-LR6, Eveready EN91,
Radio Shack 23-874 (not ATEX approved) size AA 1.5V Alkaline batteries, Eveready CH15 (not ATEX approved) or
Radio Shack 23-149 (not ATEX approved) size AA 1.2V NiCad batteries, or Eveready L91 size AA 1.5V Lithium
batteries (not CSA or ATEX approved). Substitution of batteries may impair intrinsic safety.
4.
The accuracy of the PhD Lite should be checked periodically with known concentration
calibration gas. Failure to check accuracy can lead to inaccurate and potentially dangerous readings. (The
Canadian Standards Association (CSA) requires an accuracy check using known concentration calibration gas
prior to each day’s use.)
5.
The accuracy of the PhD Lite should be checked immediately following any known exposure
to contaminants by testing with known concentration test gas before further use. Failure to check accuracy can
lead to inaccurate and potentially dangerous readings.
6.
A sensor that cannot be calibrated or is found to be out of tolerance should be replaced
immediately. An instrument that fails calibration may not be used until testing with known concentration test gas
determines that accuracy has been restored, and the instrument is once again fit for use.
7.
Do not reset the calibration gas concentration unless you are using a calibration gas
concentration that differs from the one that is normally supplied by Biosystems for use in calibrating the PhD Lite.
Customers are strongly urged to use only Biosystems calibration materials when calibrating the PhD Lite. Use of
non-standard calibration gas and/or calibration kit components can lead to dangerously inaccurate readings and
may void the standard Biosystems warranty.
8.
Use of non-standard calibration gas and/or calibration kit components when calibrating the
PhD Lite can lead to inaccurate and potentially dangerous readings and may void the standard Biosystems
warranty.
Biosystems offers calibration kits and long-lasting cylinders of test gas specifically developed for easy PhD Lite
calibration. Customers are strongly urged to use only Biosystems calibration materials when calibrating the PhD
Lite.
9.
Substitution of components may impair intrinsic safety.
10.
For safety reasons this equipment must be operated and serviced by qualified personnel
only. Read and understand this reference manual before operating or servicing the PhD Lite.
11.
A rapid up-scale reading followed by a declining or erratic reading may indicate a hazardous
combustible gas concentration that exceeds the PhD Lite’s zero to 100 percent LEL detection range.
12.
Use only the following Biosystems chargers to recharge the PhD Lite:
U.S. & Canada: 54-26-0201, 54-26-0202, 54-26-0204
Europe: 54-26-0205, 54-26-0206, 54-26-0207
U.K.: 54-26-0208, 54-26-0209
13.
Use only the following pumps with the PhD Lite:
54-26-0101 (Standard), 54-26-0102 (Plated)
