5.4 Calibration Data (CAL.2)
To view the % saturation or mg/L (ppm)
concentration calibration data, proceed from the
corresponding setup menu.
1. From the setup menu, press or
to select “
CAL.2
” for the most recent
calibration data.
2. Press
HOLD/ENTER
to view calibration
data.
3. Press
HOLD/ENTER
or
CAL
to exit.
4. Press
CAL
to return to measurement mode.
Note: “ -- -- -- -- ” indicates no calibration data exists for the selected
mode.
5.5 Electrode Data (ELE.3)
Use this menu to view the electrode data for diagnostic purposes. The
data includes; slope factor (FACT), % saturation offset (OFS), 100%
saturation mV value (HI.mV), and 0% saturation mV value (LO.mV).
To view the electrode data for % saturation or mg/L (ppm) modes, enter
from the corresponding setup menu.
The electrode slope factor will give an indication of the probe eff ciency.
It is the ratio of the actual mV produced by the probe to the theoretical
mV value. The ratio displays from 0.5 to 1.999.
The % saturation offset allows the electrode offset adjustment made in
Section 5.8 —
% Saturation Offset Adjustment
to be viewed.
1. From the setup menu, press or to select “
ELE.3
”.
2. Press
HOLD/ENTER
to enter the menu. “
FACT
” will be
momentarily shown before the slope factor is displayed.
3. Press
HOLD/ENTER
again. “
OFS
” will be momentarily shown
before the % saturation offset is displayed. Note: this is not
available from the mg/L (ppm) concentration setup menu.
4. Press
HOLD/ENTER
again. “
HI.mV
” will be momentarily
shown before the electrodes mV output at 100% is displayed.
5. Press
HOLD/ENTER
again. “
LO.mV
” will be momentarily
shown before the electrode mV output at 0% is displayed.
Press
CAL
to exit the setup mode and return to the measurement mode at
any time.
