Re-Programming Ph Measurement - Hach sensION+ MM340 Manual

4. Operation

4.8. Re-programming pH measurement

Default programming (standard)
Resolution • 0.01 pH
Measuring mode • 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 .
View mV • No
Limits • No
pH isopotencial • pHiso 7.00

Other options
• 0.1 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
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 .
