Errors during calibration 

 

 

•

 

NOT STABLE

:

 

The button 

 was pressed with still unstable signal. Wait for the icon 

 to appear 

to confirm the point.

 

•

 

WRONG BUFFER

: The buffer is polluted or not part of the recognized families. 

•

 

SLOPE OUT OF RANGE

: The slope of the sensor calibration line is out of the acceptable range 80 - 120%. 

•

 

CALIBRATION TOO LONG

: 

The calibration exceeded the time limit: only the points calibrated up to that 

moment will be kept. 

 

mV Parameter   

 

 

 

 

 

 

 

 

 

pH 70 Vio; PC 70 Vio 

•

 

In measure mode press the key 

 and move to the mV parameter indicated by the icon 

. 

•

 

The display shows the measurement in mV of the pH sensor. 

•

 

The scrolling on the display of four red bands 

 means that the measurement is not stable yet. 

•

 

Consider the measurement truthful only when the stability icon appears 

.  

 

Note

: This measurement is recommended to evaluate the sensor efficiency 

 

 

ORP Parameter (Oxide-Reduction potential)   

 

 

pH 70 Vio; PC 70 Vio 

ORP sensors can be used on this series of devices to measure the Oxide-Reduction potential. 
Connect the Redox electrode to the BNC type connector marked in green; if necessary, connect the 

temperature probe to the RCA / CINCH Temp connector always marked with a green background. 
It is possible to calibrate the sensor offset by performing automatic calibration on a predefined point. The 

instrument automatically recognizes the 

Redox solution 475 mV / 25 °C

; contact the local distributor to 

proceed with the relevant purchase. 

The instrument can correct the sensor offset by + 75 mV. 

•

 

ORP parameter Setup 

 

•

 

In measure mode press the key

 to access the SETUP menu.  

•

 

Use the directional keys to move to 

ORP SETTINGS P2.0

 and access the menu by pressing the key 

 . 

•

 

Move with the keys 

 and 

  to select the program to access. 

 

The table below shows the setup menu structure for the ORP parameter; for each program there are the 

options that the user can choose and the default value:
