  CO/CO2 measurement (testo 445) CO measurement (testo 445) The connected probe 0632.1247 is initialised during the switch- on phase (“Count Down” runs in the display). For this reason, the measuring instrument should only be switched on in an atmosphere free of CO. Values will be too low otherwise in subsequent measurements.

• Page 30: Co/Co Measurement

  (testo 445) The 0632.1240 probe measures concentrations from 0 to 1 vol % CO 2 . The unit can be switched between ppm and vol% as described in “Parameter settings” on page 16. The measuring principle is based on infrared absorption. The probe has a relatively high power consumption on account of its sensor.

Foreword

Dear Customer

You have made the right decision by choosing a measuring instrument from Testo. Every year, thousands of customers purchase our high-quality products. There are many good reasons for this.

1)We offer value for money. Reliable quality at the right price.

2)Considerably longer guarantee periods of up to 3 years — depending on the instrument.

3)With over 40 years of specialist experience we are optimally equipped to solve your measuring tasks.

4)Our high quality standards are confirmed by ISO 9001 certification.

5)It goes without saying that our instruments bear the CE mark required by the EU.

Initial operation

Please read prior to measurement

Do not measure on live parts.

Do not switch instrument on or off with the button

—during instrument configuration

—during automatic saving

Complete automatic saving before connecting instrument to the Comfort software.

If the instrument does not function remove battery and put it in again. The respective error message is shown in the display. Refer to the information on “Error messages” on page 33 of the Instruction manual.

Observe storage and transport temperature and max. operating temperature (e.g. protect measuring instrument from direct sunlight)

When changing configurations (e.g. changing the probe), the instrument should be switched off because the values specific to the probe can only be read when the instrument is switched on.

The V24 cable (PC connection) can be inserted anytime.

A simultaneous print command is not possible if the PC cable is connected.

Ensure that the contacts are correct in probes with a plug-in head.

The swivel nut in the probe handle should be securely tightened.

Opening the instrument, inexpert handling and use of force cancels your warranty.

Putting in the batteries

9V block battery is included in delivery.

Open the battery compartment at the back of the instrument.

Put in block battery. Observe polarisation.

Close battery compartment.

Refer to “Power supply” Chapter for more information on alternative power supply, charge, battery quality, charging procedure.

Observe instrument configuration when using rechargeable batteries.

Displays measurement functions

Explanation of symbols:

Counter for the log number in the memory.

When saving manually: number of a measurement saved. When saving automatically: number of a measurement series.

This counter is needed in order to be able to find single logs or a measurement series when reading the memory.

Counter for saving a measurement cycle (is only required with automatic saving).

The measurement cycle in a measurement series can be found.

Manual saving of a single measurement by pressing the save button .

Automatic saving program has been set up.

Saving is activated by pressing the button.

Symbol for reading contents of memory on display.

Symbol for deleting memory contents

If this symbol appears, the printing function is activated. The symbol flashes while data is being transmitted. You can

print on the desktop printer by pressing the print button .

Shows capacity of battery and rechargeable battery.

If the inner segment no longer appears (symbol flashes), the battery has to be changed or the rechargeable battery has to be recharged. The instrument switches itself off automatically after 1 minute.
