TA-CMI
TA-CMI is a computer programmed measuring instrument. It is a handheld instrument for
measuring differential pressure, temperature, and flow through balancing valves in hydronic
systems. It consists of a sensor unit and a instrument unit that has been programmed with the
TA valve characteristics, which makes it possible to take a direct reading of flow and differential pressures.
The TA-CMI has two main components:
• A sensor unit which contains a piezoresistive pressure sensor, one measurement valve,
connections and rechargeable NiMH batteries. The measurement valve has a safety function
which protects the sensor from too high differential pressures.
• An instrument unit which contains a micro computer, input touch pad, LCD display and
rechargeable NiMH batteries.
The instrument and the sensor units communicate wirelessly or by cable.
= Warning – read the manual.
The TA-CMI can be cleansed with a damped cloth and a lenient cleaning-agent.

Guarantee
TA-CMI is guaranteed to be free of material or performance defects in normal use and service. The
guarantee period is five years, starting from and including the day of delivery. A guarantee period
of 180 days applies for repairs and service.
This guarantee applies only for the original purchaser and does not include consumable materials
or measuring instruments which, in TA´s opinion, have been used incorrectly, have been neglected
or have been damaged as a result of accident or abnormal use or handling.
Tour & Andersson AB guarantees that its software operates in all significant respects in accordance
with its performance specification. TA does not guarantee that its software is fault-free or that it will
operate without crashing.
TA´s obligations in respect of its guarantee are restricted to full replacement of the purchase cost or
cost-free repair or replacement of defective products delivered to a Tour&Andersson AB authorised
service centre during the guarantee period, at Tour&Andersson AB's discretion. To claim service
under guarantee, either contact the nearest TA authorised service centre or send the product,
carriage-paid (FOB) and insured, to the nearest Tour & Andersson AB authorised service centre with
a description of the problem. TA does not accept the risk of damage to the product during transport.
After repair under guarantee, the product will be returned carriage-paid (FOB) to the purchaser.
If TA is of the opinion that the fault has been caused by incorrect use, modifications, accident or

FCC Notification and ETL markings
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
Caution: Changes or modifications of the equipment, not expressly approved by the party
responsible for compliance, could void the user´s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protections against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
- Consult the dealer or an experienced radio/TV technician for help.
ETL LISTED: Conforms to UL std. 61010B-1: Certified to CAN/CSA std. C22.2 No.1010.1-92

Radio frequency communication
TA-CMI uses radio frequency to communicate wirelessly between the instrument and
sensor units. Always turn off radio communication when there is risk that
TA-CMI disturbs other vital electronic devices, i.e. near medical equipment
and implanted cardiac pacemakers, in health care facilities, aircrafts, blasting
areas, areas with potentially explosive atmosperes and other areas posted
“turn off two-way radio”! You turn off radio communication by setting the radio
channel to “OFF” in the Instrument setup menu (see page 30).
Storage recommendations
• Never leave water in the sensor unit when there is a risk of freezing (i.e. in a car during
winter)!
• Storage above 40°C reduces battery life.

Note! Both the sensor unit and the instrument unit contains batteries that need to be
charged. For best charging performance keep the connector clean. The supplied charger
from TA must be used!
Following batteries must be used (user not allowed to change batteries):
Instrument unit: 3 pcs NiMh type AA/R6
Sensor unit: 2 pcs NiMh type AAA/R03
Warning! Do not open the instrument as this could damage the warranty seal and void
your guarantee! See page 2 for further information.
