pH Calibration

1. Calibration with ATC/Temp Sensor in
the pH Mode
1.1 Connect the pH sensor to the BNC
connector and the ATC/Temp sensor
to the ATC/Temp connector of the
unit. Auto icon will be on. Press the
mode key until the unit displays
pH mode.
1.2 Rinse the pH sensor and ATC/Temp
sensor in distilled water and immerse
them in the first buffer solution.
The temperature displayed is the
buffer temperature.
NOTE: If no ATC/Temp sensor is
connected, Man icon will be on, adjust
the temperature reading (0.0 to
60.0°C) to that of the first buffer,
using the [ ] and [

tion. The selected buffer icon will
flash. Press the enter key. The buffer
icon will remain on, and the calibra-
tion icons will flash until the unit
detects a stable reading. When a stable
reading is reached, the calibration
icons will stop flashing, and sensor
efficiency will be displayed momentar-
ily. The pH value of the first buffer will
then be displayed. The first point has
been calibrated.
NOTE:
If the first buffer is pH 4.00/10.00 or
(4.01/9.18) the unit will automatically
exit the calibration mode after the
first point has been calibrated.
Single point calibration is complete.
The unit cannot be further calibrated.
If the first buffer is pH 7.00 (6.86),
press the mode key to save a single
point 7 buffer calibration.
