3.4 Certification
EN 55011/CISPR 11 Notification Warning
This is a Class A product. In a domestic environment this product may cause radio interference in
which case the user may be required to take adequate measures.
Canadian Radio Interference-Causing Equipment Regulation, ICES-003, Class A:
Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
FCC Part 15, Class "A" Limits
Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC
Rules. Operation is subject to the following conditions:
1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
6 English
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
Section 4 Installation
4.1 What you have received
You should have received the following major components:
• An instrument, model 3654, with keypad, display, and handle
• A membrane-covered thermal conductivity (TC) sensor, model 3127x for H2 measurement or
model 31570 for N2 measurement.
• A flow chamber, model 32013A with flow adjustment valve for N2 analyzers, or model
32015 without flow adjustment valve for H2 analyzers
• The Hach 3654 software on a CD and a PC communications cable
• Two C-type batteries
• A sensor recharge kit in a plastic case containing materials to maintain and service your sensor

4.2 Instrument overview
Figure 1 ORBISPHERE 3654 portable analyzer
1 Pressure relief valve 4 TC sensor
2 Flow chamber 5 RS-232 port
3 Flow chamber locking nut 6 Battery cap
4.3 PC software installation
Install the PC software by inserting the accompanying CD into your PC and running the SetUp
program. Simply follow the on-screen instructions.
When finished, a new Windows Program Group labeled Orbisphere is created containing the
software and help files.
4.4 Atmospheric pressure equilibrium
As soon as you receive the instrument, it will be necessary to ensure the interior and exterior of the
instrument are both at the same atmospheric pressure. It is probable that during shipment these
pressures will become different.
To ensure the pressures are equal, simply press the pressure relief valve located on the top of the
instrument for about 5 seconds before releasing. Refer to Instrument overview on page 8.
4.5 Sensor installation
The TC sensor connects to the instrument base through a 10-pin LEMO connector. A locking pin
holds the sensor in place.
8 English
Both the membrane-covered TC sensor and the flow chamber are shipped pre-installed on the
instrument. It will, however, be necessary to remove the flow chamber when servicing the sensor.
Refer to Sensor maintenance on page 24.

1 Purge gas inlet 4 External temperature sensor
2 Output connection to portable instrument 5 Storage cap
3 Purge gas outlet
4.6 Purge gas connection
It is critical that the TC sensor has a supply of purge gas running before operating the system. The
TC sensor, when exposed to a liquid sample, will become damaged if the purge gas is not running.
CO2 is used to purge the N2 sensor and N2 or CO2 is used to purge the H2 sensor. A cylinder located
at the bottom of the instrument supplies the purge gas. This cylinder is refillable. Refer to Purge gas
cylinder refill on page 27.
The TC sensor is purged cyclically. In measurement mode, a cycle consists of a 4 second purge
followed by 16 seconds of measurement. When the instrument is in standby, the purge time is the
same, followed by a 17 minute delay. During the purge time, the flow rate varies, depending on the
pressure inside the cylinder. At least four bubbles should exit from the purge gas exit during the
purge time.
The purge gas input to the sensor uses a Tygon tube (4 mm outside/2 mm inside diameter, 110 mm
long) that attaches to the base of the sensor. Refer to Figure 2 on page 9.
The hole in the side and near the base of the sensor is the purge gas exit. To check the purge gas
flow rate, push the supplied nylon tubing into this hole, to its limit. To disconnect it again, press on
the ring surrounding the tube and pull out.
To check the purge gas flow rate, immerse the end of this tubing in water and switch on the
instrument. Gas should flow intermittently out of the tube.
Note: During normal operation, and especially when the instrument is in standby mode, ensure that the exit of the
purge gas tube is exposed to the atmosphere and not in contact with any liquid or hard surface.
4.7 Connections
4.7.1 External power supply (optional)
The instrument is usually powered by the batteries supplied. You can, however, power it from an
external power source using the model 32939 power supply adaptor as illustrated in Figure 3.
English 9
Figure 3 Model 32939 power supply
Connect the male LEMO-6 plug on the power supply adapter, to the RS-232 connector on the right
side of the instrument. The female LEMO-6 plug can then be used to connect to your PC using the
standard RS-232 cable supplied with the instrument.
Plug the transformer into your mains power supply using the cable supplied.
Note: If the external power supply is not clean, this may result in unstable measurements.
4.7.2 Instrument - PC connection
An RS-232 cable is supplied with the instrument, with a 6-pin LEMO plug on one end and a 9-pin D-
Type plug on the other.
Connection LEMO-6 Pin Description
Pin 1 Transmitted data (TXD)
Pin 2 Received data (RXD)
Pin 3 CTS
Pin 4 RTS
Pin 5 Not used

Pin 6 Not used
Pin 7 Request to send RTS
Pin 8 Clear to send RTS
Pin 9 Not used
Note: If you use an adapter for the connection to the PC, make sure it is designed for this purpose and, thus, has
all nine pins accessible. Some 25-to-9 pin adapters are supplied for specific use, such as a mouse, and these may
have only certain pins available.
It is not necessary to keep the PC connected to the instrument during measurement. This connection
is required for downloading stored measurements, real-time monitoring, reviewing and changing
configuration parameters and testing the instrument from the PC.
