Sensor Over Range Alarms; Lel Failure Due To Lack Of Oxygen Alarm; Pc Connection Via Infrared Port - Honeywell MultiPro Manual

period has elapsed or once the battery voltage
reaches 3.2 volts, the instrument will go into
alarm for the last time, notify the user that it is
shutting itself down and proceed to turn itself
off.
Alkaline battery replacement and Li-Ion
battery charging instructions are
contained in section 5.4 and 5.5.
The MultiPro must be
located in a non-hazardous location
during the charging cycle. Charging the
MultiPro in a hazardous location may
impair intrinsic safety.
The MultiPro must be
located in a non-hazardous location
whenever alkaline batteries are removed
from the alkaline battery pack. Removal
of the alkaline batteries from the battery
pack in a hazardous area may impair
intrinsic safety.
CAUTION Always turn the MultiPro off
prior to removing the battery pack.
Removal of the battery pack with the
instrument turned on may cause
corruption of stored data in the MultiPro.
2.4.6

Sensor over range alarms

The MultiPro will go into alarm if a sensor is
exposed to a concentration of gas that
exceeds its established range. In the case of
an LEL reading that exceeds 100% LEL, the
LEL channel will be automatically disabled by
the instrument and the alarm will latch (remain
on) until the instrument is turned off. The
MultiPro must be turned off, brought to an
area that is known to be safe (containing
20.9% oxygen, 0% LEL and 0 PPM toxic
gases), and then turned back on. The display
will show "---" and "OL" alternately in place of
the sensor reading for any channel that has
gone into over range alarm.
A combustible sensor
overrange alarm indicates a potentially
explosive atmosphere. Failure to leave the
area immediately may result in serious
injury or death!
In the event of an LEL
overrange alarm the MultiPro must be
→
turned off, brought to an area that is
known to be safe (containing 20.9%
oxygen, 0% LEL and 0 PPM toxic gases),
and then turned on again to reset the
alarm.
2.4.7 LEL failure due to lack of oxygen
alarm
The LEL sensor in the MultiPro requires a
certain amount of oxygen to function properly.
When oxygen levels fall below 11% by
volume, the MultiPro will show "---" in place of
the LEL reading and display "O2", "too" and
"Lo" in successive screens in the location
typically used for the LEL reading.

PC connection via infrared port

MultiPro instruments that
are equipped with a fully
enabled datalogger can be
downloaded to a PC using
BioTrak or IQ software
through the MultiPro's
infrared port. For the
location of the infrared port, see the illustration
below.
1. With the MultiPro turned off, hold the
MODE button down until four beeps are
heard. Depending on the software
version, this will normally take between 10
and 20 seconds. "PC Connect" will be
shown once the infrared port has been
activated.
2. Align the infrared port on the MultiPro with
the PC's infrared port to complete the
connection.
