WARNINGS AND CAUTIONS
1. The PhD2 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.
The accuracy of the PhD2 should be checked periodically with known concentration
calibration gas. Failure to check accuracy can lead to inaccurate and potentially dangerous readings.
4.
The accuracy of the PhD2 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.
5.
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.
6.
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 PhD2.
Customers are strongly urged to use only Biosystems calibration materials when calibrating the PhD2. Use of
non-standard calibration gas and/or calibration kit components can lead to dangerously inaccurate readings
and may void the standard Biosystems warranty.
7.
Use of non-standard calibration gas and/or calibration kit components when calibrating the
PhD2 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 PhD2
calibration. Customers are strongly urged to use only Biosystems calibration materials when calibrating the
PhD2.
8.
Substitution of components may impair intrinsic safety.
AVERTISSEMENT: LA SUBSTITUTION DE COMPOSANTS PEUT COMPROMETTRE LA SÉCURITÉ
INTRINSÈQUE.
9.
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 PhD2.
ATTENTION: POUR DES RAISONS DE SÉCURITÉ, CET ÉQUIPMENT DOIT ETRE UTILISÉ, ENTRETENU
ET RÉPARÉ UNIQUEMENT PAR UN PERSONNEL QUALIFIÉ. ÉTUDIER LE MANUEL D'INSTRUCTIONS
EN ENTIER AVANT D'UTILISER, 'ENTRETENIR OU DE RÉPARER L'ÉQUIPMENT.
10.
A rapid up-scale reading followed by a declining or erratic reading may indicate a hazardous
combustible gas concentration that exceeds the PhD2’s zero to 100 percent LEL detection range.
