Default programming (standard)
• 0.01 pH
• By stability.
- Standard criterion (variation < 0.01 pH in 6 s).
• In continuous.
- The result is stored when the measurement
has finished.
- The result is printed when the measurement
has finished.
• No
• No
• pHiso 7.00

Other options

• 0.1 pH • 0.01 pH
• By stability.
- Rapid criterion (variation < 0.02 pH in 6 s).
- Standard criterion (variation < 0.01 pH in 6 s).
- Strict criterion (variation < 0.002 pH in 6 s).
• In continuous. Selection of the time interval for:
- Data storage.
- Data printing.
• By time. Selection of the time interval for:
- Data storage.
- Data printing.
• Simultaneous display of pH and mV concerned.
• Higher and lower limits. Acoustic warning when the measure-
ment is out of limits, in the printed ticket appears "A" beside
the measured value.
pHiso 7.00 / Manual introduction / Value calculation.
Important note:
Once the measurement has been re-programmed, it will be performed in
accordance with the new parameters.
It is highly recommended to apply the same stability criteria to measure and
calibrate.
