1.0 Introduction
1.1 Warnings and Cautions
The TARGET Series gas detectors are designed to detect hazardous atmospheric conditions. An indication of life
threatening hazards should be taken very seriously. NEVER ignore an alarm condition.
W
ARNINGS
:
• Any rapid upscale combustible gas reading followed by a declining or erratic reading may indicate a gas
concentration beyond the upper-scale limit. This may indicate a flammable concentration.
• Off-scale readings may indicate a flammable concentration.
• Electromagnetic interference (EMI) signals may cause incorrect operation.
• CSA requirement: Before each day’s usage, instrument sensitivity must be tested on a known concentration of
methane between 25-50% LEL. Accuracy must be within –0 to +20% of the actual concentration applied.
Accuracy may be corrected, if necessary, by performing sensor calibration.
• Oxygen deficient conditions can cause lower combustible gas readings than actual concentrations.
• Oxygen enriched conditions can cause higher combustible gas readings than actual concentrations.
• The instrument batteries should only be charged in a non-hazardous location.
• The instrument should only be connected to a computer in a non-hazardous location.
C
AUTIONS
:
• In case of an atmospheric alarm condition, follow your organization’s established procedures for such a situation.
Evacuating the affected area is usually the first course of action, followed by ventilation and re-testing of the
environment prior to re-entry.
• Silicone compound vapors may adversely affect the TARGET instrument’s standard combustible sensor causing
lower readings than actual concentrations. If the instrument has been exposed to silicone vapors it is strongly
recommended that the instrument be recalibrated prior to its next use. Repeated exposure to silicone compounds
will prematurely destroy the standard combustible sensor.
NOTE: The optional MOS combustible sensor is much less susceptible to silicone poisoning, but instrument
calibration should take place on a more frequent schedule.
• The sensor sampling area must be kept clean. Contamination of this area can prevent proper operation of the
sensors.
Any sensor that fails calibration procedures should be replaced and recalibrated immediately.
The combustible portion of this instrument has been assessed by CSA for performance. Users may refer to ANSI/ISA
RP12.13 or an equivalent international recommended practice for guidance in the use of combustible gas detection
equipment.
TARGET instruments with a CSA logo on the serial number label are approved for Intrinsic Safety when used in Class
1, Division 1, Group A, B, C, D Hazardous Location environments.

1.2 Unpack
Unpack the TARGET Series instrument and examine it for shipping damage. If such damage is observed, notify both
ENMET customer service personnel and the commercial carrier involved immediately.
Regarding Damaged Shipments
N
OTE
: It is your responsibility to follow these instructions. If they are not followed, the carrier will
not honor any claims for damage.
This shipment was carefully inspected, verified and properly packaged at our company and delivered to the
carrier in good condition.
When it was picked up by the carrier at ENMET, it legally became your company’s property.
If your shipment arrives damaged:
• Keep the items, packing material, and carton “As Is.” Within 5 days of receipt, notify the carrier’s local office
and request immediate inspection of the carton and the contents.
• After the inspection and after you have received written acknowledgment of the damage from the carrier,
contact ENMET Customer Service for return authorization and further instructions. Have your Purchase Order
and Sales Order numbers available.
