Temperature Measurement
for Orion 310
A. Temperature Compensation
(Manual and Automatic)
1. Use an ATC probe (Orion 927005 or Orion 927006) for automatic
temperature compensation. Disable the LogR function using the
TEMP key.
2. Attach ATC probe to 3.5 mm phone jack on rear panel of the
PerpHecT pH meter. See Figure 4 .
3. For manual temperature compensation, disconnect the ATC probe.
Manual temperature may only be set when the LogR function is
disabled and there is no ATC probe connected:
Press the MODE key until the temp mode is entered. Use the
SCROLL (

the MODE key to return to pH mode. This temperature will now
be used to calculate temperature corrected pH values.
