Measuring Temperature; Temperature Standardization (Atc) - Fisher Scientific accumet AP 110 accumet AP 115 accumet AP 125 Instruction Manual

Note: enabling the AUTO read hold function can
lead to erroneous values if the electrode is slow
to respond such as testing of viscous or dirty
samples, changing temperatures, etc.

9. MEASURING TEMPERATURE

AP meters can utilize automatic temperature
compensation
compensation (MTC). The ATC may be separate or
integrated into a pH electrode. When ATC is used,
temperature is continuously updated and visible on the
display. When ATC is not used the meter will display
25 C as the default temperature. AP meters can retain
o
simultaneous temperature adjustments for both ATC
(with probe) and MTC (default temp when probe is not
used). Temperature is displayed in each Measurement
mode pH, mV, R.mV, and Ion.

9.1 Temperature Standardization (ATC)

The temperature reading of your ATC probe can be
adjusted at a single temperature value to ensure
optimal accuracy. Standardization of ATC is only
recommended when temperature errors are suspected
and/or when a replacement temperature probe is used.
1. Press mode to select mV measurement mode.
2. Press std/enter to access the Standardize screen.
'Std' is now displayed indicating this mode.
3. Dip the ATC probe (or pH/ATC electrode) into a
solution of known temperature (i.e. a certified
temperature bath). Allow adequate time for the
temperature
4. Set the temperature by using the save/▲ or
view/▼keys. The meter allows adjustment up to
±5.0 degrees compared to the factory default.
