8.3 P2.0: Viewing Previous Calibration Data (CAL)
This mode lets you recall previous calibration data,
which helps you know when to re-calibrate your meter.
This is a “view only” mode.
From measurement mode:
1. Press the SETUP key to enter Set up mode.
2. Press the MI/▲ or MR/▼ keys to scroll through
subgroups until you view parameter P2.0.
3. Press the HOLD/ENTER key to view previous
calibration data.
4. Press the HOLD/ENTER key to return to
subgroup menu.
8.4 P3.0: View Electrode Data (ELE)
This menu features data of the electrode properties for diagnostic purposes. The
“view only” parameters such as the electrode Slope Factor (k), % Saturation Offset
setting, 100% Saturation mV value and 0% Saturation mV value are very useful in
determining the life efficiency of the electrode. These electrode properties can be
examined through its data in % Saturation and mg/L (ppm) which is available in their
Set Up menu respectively.
8.4.1 EL.1 Viewing the electrode Slope Factor
This parameter lets you view and gives an indication of
the probe’s efficiency. The value displayed is the ratio of
the theoretical value and the actual value produced by
the probe. The higher the number, the lower the mV
output from the probe. The ratio displays from 0.5 to
1.999.
From the % Saturation menu,
1. Press the SETUP key to enter Set up mode.
2. Press the MI/▲ or MR/▼ keys to scroll through
subgroups until you view parameter P3.0.
3. Press the HOLD/ENTER key to enter the menu
and view the Slope Factor (K) of the electrode.
