1.5 Safety Precautions
HAZARDOUS AREA WARNING: This instrument has not been designed to be intrinsically safe
for use in areas classified as hazardous locations. For your safety, DO NOT
use it in hazardous
(classified) locations.
COMBUSTIBLE/FLAMMABLE GAS WARNING: This is NOT a safety device. Some gases
which this instrument can detect may be combustible/flammable. When properly configured, this
instrument is designed to alarm at concentrations that are lower than the explosive limit of the
gas. As such, it is the buyer’s responsibility to initiate an immediate planned response to any gas
leaks as soon as they are detected. This equipment should NEVER be used to measure or
sample gases at or above their respective lower explosive limits.
1.5.1 Explosive Atmosphere
Do not operate this equipment in the presence of flammable liquids, vapors or aerosols. Operation of any
electrical equipment in such an environment constitutes a safety hazard.
1.5.2 Misuse and Modifications to Monitor
The protection provided by the monitor may be impaired if the monitor is used in a manner not specified
by these instructions. Changes or modifications to this monitor will void the warranty.
1.5.3 Altitude Limit
6,562 ft (2,000 m)
1.5.4 Cleaning
Clean the outside of the monitor’s case using a dry cloth — DO NOT use soap and water.
1.6 Unpacking and Initial Checks
Your SF6Portable Monitor was carefully inspected at the factory before shipment, and packed so as to be
highly resistant to damage while in transport. When you receive the instrument, however, please unpack
it promptly and make a visual inspection to make sure that no damage has occurred during shipment. Also
check that all the following items have been received.

Bacharach’s Service Department for assistance (refer to Section 5.2 Service Centers).
1.7 Shipping Precaution
When shipping the instrument by air, deflate the purge-air bag to prevent it from bursting due to changes
in air pressure. Deflate the bag by selecting the EMTYBAG function as described on page 15.

1.8 Features and Capabilities
•Detects, measures, and displays the level of SF6gas in the area being monitored
•Measurement range of 0–1,000 ppm with a resolution of 1 ppm
•Self contained purge-air bag, allowing the monitor to be used in a contaminated atmosphere
•Automatically logs up to 200 gas readings that can be printed / plotted for analysis
•Eliminates false alarms with use of non-dispersive IR source and sample draw system
•Visual and audible gas alarm indictors that are turned ON when the detected gas level exceeds
a user defined trip-point
•Extensive self diagnostics, providing both visual and audible indications when a fault occurs
•Battery powered, providing 8–12 hours of operation
1.9 Functional Overview
The Bacharach Sulfur Hexafluoride (SF6) Portable Monitor is designed to detect, measure, and display the
concentration of SF6gas in the area being monitored. To ensure accurate gas measurements, the monitor
self-zeros every 4 minutes using its internal supply of fresh air.
During normal operation the SF6Monitor displays both the current gas level and the peak gas level
detected on its front panel LCD. The monitor retains a log of previous readings that can be easily accessed
at a later time for analysis.
Front panel indicators and an audible alarm are provided to signal gas alarm and instrument fault
conditions. The audible alarm can temporarily be silenced by a push of a button, but will reactivate if the
gas level is still above the alarm trip point after a user-defined time period has elapsed.
The SF6Monitor requires only minor periodic maintenance such as the occasional replacement of filters.
The monitor incorporates active diagnostics that continuously check the system for proper operation. A
front panel indicator is provided to alert an operator of system malfunctions, and fault codes are generated
that enable the operator to quickly identify the cause of the fault.

3 Operation
3.1 Front Panel Display and Controls
3.2 Connecting Gas-Sample & Exhaust Lines
3.2.1 Overview
A single gas-sample line needs to be run from the SF6Monitor to the area to be monitored. If desired, an
optional exhaust line can be installed to vent SF6gas away from the monitor.
3.2.2 Connecting the Gas-Sample Line
To connect the gas-sample line to the monitor, simply push the tubing onto the elbow connector and attach
the elbow to the Gas Sample Port on the front of the monitor as shown in the illustration below.
The gas-sample line can be up to 50 ft (15.2 m) in length. All tubing bends should have a radius of no less
than 5" to insure proper airflow. If kinks or obstructions occur in the line the monitor may not function
properly.
The end of this line should be placed near the potential leak source and positioned to reduce the possibility
of mists, aerosols, oil, water, dust, or other contaminates being drawn into the monitor.
An external filter (P/N 3015-5324) should be attached to the end of this line. See figure below.

SF6Portable Monitor
10 Instruction 3015-5150
3.2.3 Connecting the Exhaust Line (optional)
The optional exhaust line carries the exhausted gas sample away from the monitor.
The exhaust line can be up to 50 ft (15.2 m) in length. Ideally this line should terminate outdoors in a
location that is not exposed to the elements.
Connect the exhaust line to the monitor by firmly pushing the tubing into the Exhaust Port’s push-to-
connect (PTC) fitting. (See previous figure.) If the exhaust line terminates outside the building, position
the tubing so that no water or moisture can enter the line. Note that this line does not require a
termination filter.
To connect the exhaust line to the exhaust
port’s PTC fitting, firmly push the appropriate
tubing into the hole in the center of the
connector until it seats in the connector. Refer
to the figures at the left.
To remove tubing from a PTC connector, push
and hold the spring-loaded collar inwards,
then simultaneously withdraw the tubing.
Refer to the figures at the right.
