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.
> Do not perform contact measurements on non-insulated, live
parts.
> Do not store the product together with solvents. Do not use any
desiccants.
> 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 relate only to the measuring
range of the sensors. Do not expose handles and feed lines to
temperatures in excess of 40 °C (104 °F), unless they are
expressly permitted for higher temperatures.
> After the final measurement, allow probes and probe shafts to
cool down sufficiently in order to avoid burns from the hot
sensor tip or the probe shaft.
> Improper use of rechargeable batteries can lead to destruction
or injuries by means of current surges, fire or escaping
chemicals. The following instructions must be observed to avoid
such hazards:
• Only use in accordance with the directions in the instruction
manual.
• Do not short, take apart or modify.
• Do not expose to heavy impacts, water, fire or temperatures
above 60 °C.
• Do not store in the proximity of metal objects.
• Do not use leaky or damaged rechargeable batteries. In the
event of contact with battery acid: Thoroughly wash affected
area with water and consult a doctor, if necessary.
• Only charge in the instrument or the recommended charging
station.
• Immediately stop the charging process if this is not
completed in the given time.

• In the event of improper function or signs of overheating,
immediately remove the rechargeable battery from the
measuring instrument/charging station. Caution:
Rechargeable battery may be hot!
Use
> Please read this documentation through carefully and

5First steps
5.1. Commissioning
Initial charging of rechargeable battery
The testo 480 is delivered with a partially charged battery. Charge
the battery fully before using it for the first time.
1. Connect the mains unit to the mains socket (3).
2. Connect the mains plug to a power socket.
- Battery charging is started: status LED (4) lights up.
- The battery is fully charged: status LED (4) is off.
3. Disconnect instrument from the mains unit.
- After initial charging of the rech. battery, the instrument is ready
for use.
Switching on
1. Switch the instrument on with [ ].
- The start screen appears.
For initial commissioning or after a factory reset, the Initial
operation menu is opened automatically. Set the required menu
language:
> Call up the required selection list with [ ].
2. Select the language with [ ] and confirm with [ ].
- Instrument language is changed.
3. Set the date and time with [ ] and [ ] and confirm with [
].
4. Select ISO/US units with [ ] and confirm with [ ].
The setting only relates to the measured values and can
be individually adjusted for each measurement value if
required.
5. [ ] → Save and close.

5 First steps
17
- The current measurement values are displayed. The instrument
is now operational.
Switching off
Unsaved measurement values are lost when the
instrument is switched off.
> Switch the instrument off with [ ].
Connecting probes / sensors
Probes are detected automatically by the instrument.
Make sure the connections are secure, but do not use force!
> Insert the probe connector into the probe socket:
• Bottom of the instrument: TC probe (type K)
• Top of the instrument: digital probe:
Push/pull plug-in connections protect digital probes from
being unintentionally disconnected from the instrument.
> Connect pressure tubes to +and -.
Caution! Danger of injury caused by the pressure tube
jumping away from the connection socket!
> Ensure correct connection.
Removing probes
Thermocouple (TC) probe:
> Unplug connector from the socket.
Digital probe:
1. Pull back outer sleeve to release the push/pull plug-in
connection.
2. Unplug connector from the socket.

5 First steps
18
Connecting the mains unit
If the mains unit is connected, the instrument is powered
automatically via the mains unit.
When power is supplied via the mains unit, the instrument
may heat up. This may increase the measurement
uncertainty during TC measurement.
1. Plug the mains unit instrument connector (art. no. 0554 8808)
into the mains socket on the bottom of the instrument.
2. Plug the mains unit plug into a mains socket.
- The instrument is supplied with power via the mains unit and
battery charging begins automatically.
