Using the product

Mains unit / rechargeable battery

The rechargeable battery is permanently installed and can only be changed by a Testo service centre.

The measuring instrument is supplied with a partially charged rechargeable battery.

> Charge the rechargeable battery fully before using the measuring instrument.

Charging the rechargeable battery

The rechargeable battery can only be charged at an ambient temperature of ±0 to +35°C. If the battery has been discharged completely, the charging time at room temperature is approx. 5-6 hrs.

Charging in the measuring instrument

1. Connect the plug of the mains unit to the mains unit socket on the measuring instrument.
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 battery is fully charged.

Battery care
> Do not fully exhaust the rechargeable battery.

> Only store instrument with battery charged and at low temperatures, but not below 0°C (best storage conditions with a charge level of 50-75% = 2 segments, at an ambient temperature of 10-20°C, recharge completely before use).

> The rechargeable battery life depends on the storage, operating and ambient conditions. The available useful life of the rechargeable battery reduces more and more with frequent use. If the useful life is significantly shortened, the rechargeable battery should be replaced.

Measuring

Preparing for measurement

Zeroing phases

Gas sensors
If flue gas measurement () or ambient CO measurement () is configured, the gas sensors are zeroed when the instrument is switched on (zeroing phase).

The flue gas probe must be in the open air during the zeroing phase!

Pressure sensor
If draught measurement ()or differential pressure measurement () is configured, the pressure sensor is zeroed when the instrument is switched on (zeroing phase).

Measuring the combustion air temperature
During the zeroing phase, the temperature is measured via the thermocouple of the flue gas probe. This temperature is permanently accepted by the instrument once the zeroing phase has been completed. All dependent parameters are calculated using this value. However, ensure that the flue gas probe is near the intake duct of the burner during the zeroing phase.

Using the flue gas probe

Checking the thermocouple

The thermocouple of the flue gas probe must not lie against the probe cage.

> Check before use. Bend the thermocouple back if necessary.

Aligning the flue gas probe

The flue gas must be able to flow freely past the thermocouple.

> Align the probe by turning it as required.

The tip of the probe must be in the core current of the flue gas flow.

> Align the flue gas probe in the flue gas duct so that the tip is in the core current (area of the highest flue gas temperature).

Setting fuel

To carry out a flue gas measurement, the fuel must be set correctly, see Measurements configuration menu.
