2.2. Ensure safety
> Only operate the product properly, for its intended purpose and
within the parameters specified in the technical data. Do not
use any force.
> Dangers may also arise from the systems being measured or
the measuring environment: Note the safety regulations valid in
your area when performing the measurements.

2 Safety and the environment
5
> Do not perform contact measurements on non-insulated, live
parts.
> Do not store the product together with solvents. Do not use any
desiccants. These substances may impair the operation and
reliability of the instrument.
> Carry out only the maintenance and repair work on this
instrument that is described in the documentation. Follow the
prescribed steps exactly. Use only original spare parts
from Testo.
> Temperatures given on probes/sensors relate only to the
measuring range of the sensors. Do not expose handles and
feed lines to any temperatures in excess of 70 °C unless they
are expressly permitted for higher temperatures.
For products with Bluetooth® (optional)
Changes or modifications that have been made without the explicit
consent of the responsible approval authority, may cause the
retraction of the type approval. Data transfer may be disturbed by
equipment that uses the same ISM band, e.g. WLAN, microwave
ovens, ZigBee.
The use of radio communication links is not permitted in aeroplanes
and hospitals, among others. For this reason the following points
must be ensured before entering:
The data transfer function must not be active.
2.3. Protecting the environment
> Dispose of faulty rechargeable batteries/spent batteries in
accordance with the valid legal specifications.
> At the end of its useful life, send the product to the separate
collection for electric and electronic devices (observe local
regulations) or return the product to Testo for disposal.

4.2. Basic properties
Power supply
Power is supplied to the testo 315-3 via:
• Rech. batt., type: Li-Po rechargeable battery pack, 3.7 V/1,500
mAh (can be replaced via Testo Service)
• USB mains unit inc. cable (0554 1105), 5,0 V/1.000 mAh
With an attached mains unit, power is supplied automatically via
the mains unit and the instrument's rechargeable battery is
charged. To avoid destroying the rechargeable battery, only charge
it at an ambient temperature of 0 to 45 °C/32 to 113 °F.
5First steps
Switching on
Connect the humidity/temperature module (0636 9725)
before switching the instrument on (option).
1. Switch the instrument on: press [ ] briefly.
- All segments of the display light up for around 1 s.
- The warm-up phase then occurs for 30 s. (information in
display: warm-up).
During first commissioning, the configuration menu is
opened automatically, see Settings.
- The current measurement values are displayed. The instrument
is operational.
The measurement value of the CO sensor is displayed
in the upper line.
The measurement value of the CO2sensor is displayed
in the lower line.
Switching off
2. Switch off the instrument: press and hold down [ ].

yes selected:
CO2value is adjusted to the nominal value
and stored (only possible with a current CO2
value < 650 ppm)
The calibration/adjustment must be
carried out in fresh air that has a
normal CO2concentration of
approx. 400 ppm.
To avoid incorrect calibra-
tion/adjustment values, calibration
should, for example, not be carried
out on busy roads or in closed rooms.
Ensure that, before and during the
calibration/adjustment, no exhaled air
reaches the instrument.
Before completing the adjustment, the
instrument should be left in the fresh
air for 3-4 minutes.

Humidity, temperature and dew point
measurements are possible with the
temperature/humidity module
(accessory).
The display is
illuminated also after
the testo 315 - 3 is
switched off
The display illumination goes out as
soon as the instrument has shut down.
While the display is illuminated, the
instrument cannot be switched on.

The current measuring value is over
10,000 ppm.
The CO2 reading is
implausible.
The gas opening on the back of the
instrument might be covered. This
means that a correct CO2
measurement is not possible.
