1 DESCRIPTION OF THE PM305 AND PC705
The PM305 and PC705 Pressure Calibrator series are designed as
self-contained, portable pressure meters that have been calibrated to
precision pressure equipment traceable to national standards.
Each unit is marked with:
•
Certificate Number
•
Safety code and gas
group
•
Calibration certificate
•
Serial number
•
Production year
•
Pressure range.
1.1 CALIBRATION LABEL
Scan-Sense AS certifies that this product meets published
specifications at the time of shipment from the factory. Scan-Sense AS
further certifies that its calibration measurements are traceable to
accredited international standards. Each pressure calibrator has a
calibrated label showing the last date of calibration and the date when
the next calibration is due. Calibration is scheduled annually, unless
you believe the unit to be defective, whereupon the unit will be
calibrated after repair and receive a new label showing the date
calibrated and the new calibration-due date. Check the calibrated label
to ensure the Pressure Meter Calibrator has a valid calibration date
before using the unit. Calibration must be done by Scan-Sense AS
or a certified supplier/service center.
1.2 CERTIFICATION
Scan-Sense AS certifies that the PM305 and PC705 comply with its
published list of specifications at the time it was manufactured. ScanSense AS also certifies that its calibration measurements are traceable
to Norwegian Accreditation and to the calibration facilities of other
International Standards Organization (ISO) members. Scan-Sense AS
confirms that the PM305 and PC705 complies with the following
standards:
EMC 89/336/EEC as amended by EC Directive
92/31/Eec and the European Low Voltage Directive
73/25/EEC, amended by 93/68/EEC. To ensure
compliance, please use screened/shielded serial
communication leads (RS232).

1.3 WARRANTY
This product is guaranteed free from defects in material and
workmanship for one (1) year from the date of shipment. During this
warranty period, Scan-Sense AS will, at its option, either repair or
replace the PM305 and PC705 should it prove to be defective. The
product must be returned to a service facility designated by ScanSense AS for warranty service or repair. The foregoing warranty will not
apply to defects resulting from improper maintenance by the purchaser,
purchaser-supplied software or interfacing, unauthorized modification or
misuse, operation exceeding the environmental specifications for the
PM305 and PC705, or improper site preparation. No other warranty is
expressed or implied by Scan-Sense AS, and Scan-Sense AS shall not
be liable for any direct, indirect, special, incidental or consequential
damages, whether based on contract, tort, or any other legal theory.
1.4 CONVENTIONS USED IN THIS DOCUMENT
We have provided this section of the Handbook to help you identify
noteworthy symbols, terms and conventions used in this handbook.
Look for the following:
Symbol used to
identify an action that
can cause personal
injury or damage to
equipment.
Conformité
Européenne
Terms and definitions:
We define calibration as being
able to compare the ability of
the equipment to perform to a
known standard. Pressure
calibration provides a means of
quantifying uncertainties in
pressure measurement in order
to optimize sensor and/or
system accuracy.
1.5 SAFETY PRECAUTIONS
Following these safety precautions should ensure safe operation of the
pressure meter and your personnel safety. Be careful when working in
hazardous areas as any electrical spark could result in an atmospheric
explosion/fire.
•••• Do not use the instrument at ambient temperatures above 50°C.
•••• Do not connect to RS232 port in hazardous area.
•••• Do not apply voltage to the CURRENT input terminal.
•••• Do not remove the rear panel.
•••• Connect only Scan-Sense manufactured sensors to the External
Sensor connector.

1.6 BATTERY CHARGING INFORMATION
•••• Do not charge battery in hazardous areas.
•••• Use only the battery charger supplied by Scan-Sense AS
From a completely discharged condition, battery-charging time is about
14 hours, at a maximum charging current of 65mA.
When the battery is charged, it will provide power for about 35 hours of
continuous operation if the display back-light is defined as OFF, (and
with no RS232 connection).
In safe areas, the Pressure Meter Calibrator can be operated with all
Inputs and Outputs, and with the battery charger connected. The
Battery Charging time will increase depending on connections and
display back-light settings.
1.7 PM305/PC705 NOT OPERATING/FAILED
Repairs must be done by manufacturer or supplier certified for
service/repair of intrinsically safe equipment. Replacement batteries
and fuses must be obtained from the manufacturer.
