E. Operation
This chapter describes the steps that have to be executed frequently when using the
product.
Please read this chapter carefully. The following chapters of this document will assu-
me you are already familiar with the content of this chapter.
E.1 Mainsunit/rechargeablebattery
If the mains unit is connected, the measuring instrument is automatically powered from
the mains unit. It is not possible to charge the rechargeable battery in the measuring
instrument during operation.
E.1.1 Changingthebattery
The measuring instrument must not be connected to a mains socket via the mains
unit. The measuring instrument must be switched off. Change the rechargeable bat-
tery within 60 minutes, otherwise instrument settings (e.g. date/time) will be lost.
1 Place the measuring instrument on its front.
2 Loosen screws with a Philips screwdriver, release
clip in the direction of the arrow and remove ser-
vice cover.
3 Open the rechargeable battery compartment:
Press the orange key (À) and push in the direction
of the arrow (Á).
4 Remove the rechargeable battery and insert a new
one. Use only Testo 0515 0100 rechargeable bat-
teries!
5 Close the rechargeable battery compartment:
Press the orange key and push against the direc-
tion of the arrow until the rechargeable battery
engages.
6 Replace and close service cover (clip must click
in), x with screws.
15

E.1.2 Chargingbatteries
The rechargeable battery can only be charged at an ambient temperature of ±0...+35°C.
If the rechargeable battery has discharged completely, the charging time at room tem-
perature is approx. 5-6 hrs.
Charging in the measuring instrument
The measuring instrument must be switched off.
1 Connect the plug of the mains unit to the mains unit socket on the measuring instru-
ment.
2 Connect the mains plug of the mains unit to a mains socket.
- The charging process will start. The charge status will be shown on the display.
The charging process will stop automatically when the rechargeable battery is fully
charged.
Charging in the charger (0554 1103)
Refer to the documentation that comes with the charger.
Battery care
If possible, always discharge the rechargeable battery and recharge it fully.
Do not store the battery for long periods when discharged. (The best storage condi-
tions are at 50-80 % charge level and 10-20 °C ambient temperature; charge fully
before further use).
E.1.3 Operation with the mains unit
1 Connect the plug of the mains unit to the mains unit socket on the measuring instru-
ment.
2 Connect the mains plug of the mains unit to a mains socket.
- The measuring instrument is powered via the mains unit.
- If the measuring instrument is switched off and a rechargeable battery is inserted, the
charging process will start automatically. Switching the measuring instrument on has
the effect of stopping rechargeable battery charging and the measuring instrument is
then power ed via the mains unit.
16

E.2 Probes/sensors
E.2.1 Connectingprobes/sensors
Sensor socket:
Sensor detection is carried out at the sensor socket during the activation process:
Always connect the sensors you need to the measuring instrument before switching
it on or switch the device on and then off again after a change of sensor so that the
correct sensor data are read into the measuring instrument.
Flue gas socket:
Probe/sensor detection at the ue gas socket is carried out continuously. It is possib-
le to change the probe/sensor even while the measuring instrument is switched on.
Connectinguegasprobes
Plug the connector onto the ue gas socket and
lock by turning it clockwise gently (bayonet lock).
There must be no more than two extension leads
(0554 1202) between the measuring instrument
and the ue gas probe.
Connecting other sensors
Insert the connector of the sensor into the sensor
socket.
Connectingthepressuretube
Connect the pressure tube/tubes to the connec-
ting nipple/nipples of the pressure socket(s).
17

E.2.2 Replacingtheprobemodule
1 Press the key on the top of the probe handle and
remove the probe module.
2 Fit a new probe module and engage it in place.
E.3 Regular care
E.3.1 Condensate trap
The ll level of the condensate trap can be read from the markings on the trap. A war-
ning message is displayed if the level in the condensate trap reaches 90% ( , red as-
hing light).
Emptying the condensate trap
The condensate consists of a weak mix of acids. Avoid contact with the skin. Make
sure that the condensate does not run over the housing.
Condensate entering the gas path.
Damage to the sensors and ue gas pump!
Do not empty the condensate trap while the ue gas pump is in operati-
on.
1 Hold the measuring instrument so that the con-
densate outlet points up.
2 Open the condensate outlet of the condensate
trap: Push out plug maximum to the stop).
3 Let the condensate run out into a sink .
4 Mop up any remaining drops on the condensate
outlet using a cloth.
5 Close the condensate outlet.
The condensate outlet must be completely closed
(marking), otherwise measuring errors could occur
if external air gets in.
18

E.3.2 Checking/replacingtheparticlelter
Checkingtheparticlelter:
Check the particle lter of the modular ue gas
probe for contamination at regular intervals: Check
visually by looking through the window of the lter
chamber.
Replace the lter if there are signs of contamination
Replacingtheparticlelter:
The lter chamber may contain condensate
1 Open the lter chamber by turning it gently anti-
clockwise.
2 Remove the lter plate and replace it with a new
one (0554 3385).
3 Fit the lter chamber again and close it by turning it
gently clockwise.
E.4 Basic operating steps
