SAFETY INFORMATION
1. IMPORTANT: Read and understand this manual prior to use.
2. IMPORTANT: Oxygen instruments will show high readings for up to
30 minutes if taken from warm air to cold temperatures and vice-versa. For best
results let them “soak” in the ambient conditions prior to use.
3. WARNING: Substitution of components may impair intrinsic Safety.
4. WARNING: This instrument contains a lithium battery which may leak
or explode if improperly used. DO NOT DISPOSE OF IN A FIRE.
5. WARNING: Only service in an area known to be free of combustible
gases.
6. WARNING: Instruments are not certied intrinsically safe in
environments above 21% oxygen.
7. WARNING: To verify operation prior to each day’s use a function test
(bump test) should be performed. If the instrument does not pass this test, full
calibration should be performed.
8. WARNING: Keep all openings free from dirt, debris and foreign
objects.
9. WARNING: Do not use a damaged or improperly operating
instrument. Contact a service representative immediately.
ONLY zero instrument in a gas free environment
SEULEMENT l’instrument zéro dans un gas libèrent l’environnenment.
WARNING: To maintain intrinsic safety, service must be performed by factory
authorized technicians with approved
replacement parts only.
AVERTISSEMENT: Pour maintenir la sûreté intrinsèque, service doit être
exécuté par les techniciens autorisés par usine avec les pièces de rechange
approuvées seulement.

GENERAL DESCRIPTION
The SENSIT P100 is an exceptionally rugged personal gas
monitor. The P100 is available in single gas congurations only.
Preset alarms provide visual, audible and vibration alerts for low
and high alarm conditions. Built-in “Time Weighted Average”
(TWA) and “Short Term Exposure Limit” (STEL) alarms provide
even greater margin of safety for the user. A custom display
provides the user with easy to view information including gas
concentration, time remaining in months to sensor replacement,
battery low alert and activation of calibration process. (See
Figure 1)

ALARMS
The SENSIT P100 has two basic styles of alarm. Low Alarms
activate at two second intervals while High Alarms activate at
one second intervals. All O
2
alarms are High Alarms.
The sound, LEDs and vibrating motor are sequenced during
alarms. The alarm settings are controlled during the set-up of the
product. All instruments are preset for the standards that need
to be adhered for various locations and needs. Fig. 2 shows
examples of some of the alarm ranges.
Other alarm ranges are supplied upon request and appropriately
marked with your shipment.

ALARM ADJUSTMENT
See NEXT PAGE of this manual for Alarm Adjustment instructions.
FUNCTION (BUMP) TEST - MANUAL
Turn the instrument on and wait for the working display to
illuminate. Apply an approved concentration of gas to the sensor
area using the P100 calibration adapter. The ow should be 200-
400 cc/min. The alarm should occur in less than 20 seconds.
To verify the operation of this product this test should be done
prior to each day’s use. Failure to pass this test may indicate a
product failure or the need for calibration.
PRODUCT FEATURES
The SENSIT P100 is constructed of durable ABS plastic. The top
housing is additionally protected with a shock absorbing material
to protect the instrument from the rigors of eld use. The front
of the instrument has an opening for the sensor and sounder.
These are sealed to maintain the integrity of the IP65 rating. Two
buttons operate the instrument. The left button is for power while
the right is for zeroing and performing calibration. Multiple LED’s
beneath the frosted area create a very bright warning even in
bright sunlight.
The instrument is mounted using a sturdy suspender clip on the
back of the instrument. This instrument cannot be powered off or
zeroed when in alarm mode.
All sensors and batteries are designed for 2 years of continuous
normal use. The on-board memory will store up to 100 events or
alarm conditions. These can be downloaded through the use of
SCal-100 with SmartLink Software. Oldest events are over-written
automatically when the maximum is reached.
