Re-Programming Ph + Ec Measurements - Hach senslON+ MM 374 Manual De Instrucciones

4. Operation
4.10. Re-programming pH+EC measurement
Default programming (standard)
Resolution
• 0.01 pH
Isopotential pH • pHiso 7.00
TC • linear, TC = 2.00 % / ˚C.
TRef
• 25 ˚C
Measuring mode • By stability.
pH, standard criterion (variation < 0.01 pH in 6 s).
EC, variation < 1 digit in 6 s.
• In continuous.
- The result is stored when the measurement
has finished.
- The result is printed when the measurement
has finished.

Important note:
pH+EC MEASURE
- Once the measurement has been re-programmed, it will be performed in accordance with the new parameters.
Channel 1
- It is highly recommended to apply the same stability criteria to measure and calibrate.
