2.14 Lock/Unlock Keypad Functions (White Box)
You can Lock/Unlock the front panel keypad functions by pressing & holding
the key for 3 seconds. When in lock mode, the lock icon comes on and the
configuration menu will be inactive (Config, Set, Yes, No). When in unlock
mode, the Unlock icon comes on and all the keys are active.
2.15 pH & RTD Input Chart Recorder
Model CTXL-pH takes pH probe and RTD sensor directly. The pH probe can be
connected directly to the recorder via a BNC connector. The RTD sensor from
the pH probe can be connected to the terminal block below the BNC connector.
The recorder measures the pH and RTD temperature inputs. It compensates the
pH input for the RTD temperature. If the pH probe does not include an RTD
sensor, you need to add a 110 ohms resistor (included with the recorder) across the
terminal block. This will set the temperature input to a fixed value (about 26ºC).
pH Input Calibration Procedure
The pH input is calibrated at 4 & 7 pH values. From the Hyper terminal, you can
use the following PC commands to calibrate the pH input:
I1L<CR> Channel 1, Calibrate @ 4 pH @ 25ºC Buffer (+177.5 mV)
I1U<CR> Channel 1, Calibrate @ 7 pH @ 25ºC Buffer (0 mV)
I1C<CR> Save pH Calibration
RTD Temperature Input Calibration Procedure
The RTD input is calibrated at 20 & 80ºC values. From the Hyper terminal, you
can use the following PC commands to calibrate the RTD input:
I2L<CR> Channel 2, Calibrate @ 20ºC (RTD = 107.8 ohms)
I2U<CR> Channel 2, Calibrate @ 80ºC (RTD = 130.9 ohms)
I2C<CR> Save Temperature Calibration
pH Offset Adjustment Procedure
pH sensors will deteriorate and drift over time. You can
introduce an offset to the pH channel to compensate for
this drift. From the Hyper terminal, you can use the
following PC commands to introduce pH offset:
OF5<CR> Int0.05 pH offset
OF125<CR> Int1.25 pH offset
OF-7<CR> Introduce -0.07 pH offset
OF-175<CR> Introduce -1.75 pH offset
OFD<CR> Resets the pH offset back to Zero
OFC<CR> Displays the current pH offset value,
for example: 0020 means +0.20 pH
*NOTE: <CR> is the carriage return key
on your PC keyboard
