1. Fundamental safety instructions
5
Please read the following safety instructions with care:
Avoid electrical hazards:
Never make measurements with the unit and its external probes on or near live components unless
the unit is expressly approved for current and voltage measurements.
Damaged mains cables must only be replaced by authorised personnel.
The transmitter should be wired when disconnected.
You must always comply with the regulations applicable in your country to the opening and repair of
electrical equipment.
Protect the instrument:
Note the measuring ranges of the sensor! Overheating will destroy the probes.
Keep to the admissible storage and transport temperature and the permitted operating temperature!
Product safety / preserving warranty claims:
Operate the instrument only within the parameters specified in the technical data.
Handle the instrument properly and according to its intended purpose.
Never apply force!
Do not use the device for control purposes at the same time as operating or servicing the transmitter.
Open the instrument only when this is expressly described in the Operating Instructions for
maintenance purposes.
Carry out only the maintenance and repair work that is described in the instruction manual. Follow
the prescribed steps exactly. For safety reasons, use only original spare parts from Testo.
Any additional work must only be carried out by authorised personnel. Testo will otherwise refuse to
accept responsibility for the proper functioning of the instrument after repair and for the validity of
certifications.
Installation, setting and calibration work must only be carried out by authorised personnel.
Ensure correct disposal:
Send the instrument directly to us at the end of its useful life. We will ensure that it is disposed of in
an environmentally friendly manner.

The low-cost flow transmitter can be combined with the standard
flow probes of the reference class (see table on page 8). Vane, hot
ball and hot wire probes can be connected. The device will then
be configured for all standard applications in heating, ventilation
and air-conditioning.
Flexible analogue outputs with current or voltage output permit
easy connection to common control units or analysing units.

7. Compensation for thermal probes
9
Testo calibrates the thermal
probes at a reference pressure of
1013 hPa. If the ambient or
process pressure in the particular
application differs from the
reference pressure (1013 hPa), the
average absolute pressure should
be entered for the flow transmitter
for automatic pressure
compensation. Otherwise the true
velocity can be calculated from the
following formula:
V true = V display ✱correction factor
-or-
V true = V display ✱1013 [hPa]

8. Configuration of connections
- Channel 2 only supplies a temperature signal if a probe that also
contains a temperature sensor is connected.
- The transmitter only has to be supplied with voltage via one
channel; the other connections are bridged and serve for looping.
- The scaling data of the analogue output are adapted to the
measuring range of the probes as standard.
Note
For voltage output 0...1 V or 0...10 V also connect solder bridge
0/4.
Soldering work must only be carried out when the device is de-
energized, otherwise the electronics can get damaged.
Watch out for equipotential bonding!

9.2 Current/voltage measurement (4-wire system)
9.1 Description of the 4-wire system
In the 4-wire system the device is supplied via a separate
voltage supply (24 V DC). The outputs then actively supply the
respective current or voltage signal.
In the testo flow transmitter the power supply is galvanically
isolated from the analogue outputs.

10. Troubleshooting
If faults occur which are not described here, please consult Testo’s customer service department (see
customer service address).
Faults when switching on:
Fault Possible causes Remedy
Currents < 3.8 mA Sensor breaks Have Testo replace the sensor
(for 4...20 mA version) No probe connected Connect the probe
Currents >21 mA Sensor faulty Have Testo replace the sensor
(for 4...20 mA version) Scaling not suitable for Check measuring range
