If necessary for pH calibration point 1, modify the buffer value using the up/down arrows. Insert the sensor
into the point 1 buffer, wait until the sensor reading is stable and confirm with ENTER.
Repeat the operation with the point 2 buffer. Before putting the sensor in the point 2 buffer, clean the
sensor with distilled water and dry it well (with tissue paper) to avoid contamination of the buffer. If at any
time during the calibration process you are not sure of the calibration, you can exit without confirming by
pressing ESCAPE.

Select the type of flow meter:
- Low Freq:
Low frequency flow meter. Flow meters with pulse frequencies of between a minimum of 1 pulse every
200 seconds and a maximum of 30 pulses per second (30 Hz).
- K (l/p):
This type of flow meter requires entry of the configuration value the manufacturer indicates in litres/pulse.
- Time Q=0:
In these flow meters, which calculate the flow rate from the time between two consecutive pulses, a wait
time from which the flow rate is considered to be zero needs to be defined.
- High Freq:
High frequency flow meter for Hall effect or electromagnetic insertion flow meters with a maximum of
300 Hz (300 pulses per second).
- K-factor (p/l):
This type of flow meter requires entry of the K-factor (pulses/litre), corresponding to the diameter where it
is installed. This value is supplied by the manufacturer.
