Page 12: First Steps
5 First steps First steps 5.1. Commissioning 5.1.1. Installing the sensor Before the instrument is switched on the electrode cable must be connected. 1. Plug the BNC-plug of the electrode into the socket and turn clockwise to lock. 2. Plug the external NTC-sensor with Mini-DIN plug or blanking plug into the socket. -
Page 13: Calibrating The Instrument
Single-point calibration serves the purpose of quickly adapting the instrument to the electrode. The following buffers can be used for this purpose: • Testo buffer pH 4, pH 7, pH 10 • DIN buffer pH 4.008 ; pH 6.865 ; pH 9.18 Also pay attention to the application information for the buffer used. - Page 14 After max. 10 min. the calibration process is aborted, the electrode is most likely defective, in this case consult our service department. Contact data see back of this document or website www.testo.com/service-contact. The display shows 2. This menu option is needed for two- point calibration, see Two-point calibration page 16.

Page 15: Two-Point Calibration
Two-point calibration serves the purpose of accurately adapting the instrument to the electrode. The following buffer sets can be used for calibration: • Testo buffer set pH 4/7, pH 4/7/10 • DIN buffer set pH 4.008/6.685 , pH 6.865/9.18 Also pay attention to the application information for the buffer used. - Page 16 After max. 10 min. the calibration process is aborted, the electrode is most likely defective, in this case consult our service department. Contact data see back of this document or website www.testo.com/service-contact. The display shows 9. Rinse the electrode in water, dab off and place it into the second buffer solution 10.
