Allow a couple of minutes for the probe
to stabilize.
• Use the "VC" or "WC" key to set the
reading on the secondary LCD to that of the hot
water
• Press CFM to confirm. The meter returns to normal
operational mode.

All the meters are factory calibrated for mV.
The ORP electrodes are interchangeable and no mV calibration is
needed when they are replaced.
If, for any reason, the mV measurements are inaccurate, mV
recalibration may be carried out.
For an accurate recalibration, contact your dealer or the nearest
Hanna Customer Service Center.
• Attach to the electrode BNC connector a mV simulator with a
range of at least ±500.0 mV and an accuracy of ±0.1 mV.
• With the instrument off, press and hold CFM and then the ON
switch. The "CAL" indicator will come on and the primary LCD will
show 380.0 mV.
• Set 380.0 mV on the simulator.
• Wait for 3 sec. and press CFM. The LCD will display -380.0 mV
asking for this value to be set.
• Set -380.0 mV on the simulator.
• Wait for 3 sec. and press CFM. The LCD will display 500.0 mV.
• Set 500.0 mV on the simulator.
• Wait for 3 sec. and press CFM. The LCD will display -500.0 mV.
• Set -500.0 mV on the simulator.
• Wait for 3 sec. and press CFM.
• The secondary LCD will display 0.0C. It is now possible
to proceed with the temperature calibration, if neces-
sary, as described above, or return to normal operation
by pressing CAL.

Temperature has an effect on pH. The calibration buffer solutions are
affected by temperature changes to a lesser degree than normal
solutions. During calibration the meter will automatically calibrate to
the pH value corresponding to the measured or set temperature.
For instance, if the buffer temperature is 25C, the display will show
pH 4.01 or 7.01 or 10.01. If the buffer temperature is 20C, it will
show pH 4.00/7.03/10.06 or at 50C, the display will show pH 4.06/
6.98/9.82.
