1. Introduction
1.1 pH Cube Front Panel and Controls
Display
• 12.7mm LED display with mode enunciator.
Function Switch
• Switches between pH, mV and Temperature modes. See section 2.
Calibrate Control
• Used for pH asymmetry calibration in pH6.88 or pH7.00 buffer. See section
3.
Slope Control
• Used for pH slope calibration in a buffer that is at least 2 to 3 pH away from
pH7.00, eg. pH4.00, pH9.23 or pH10.00. See section 3.
Manual Temp Control
• Used to manually set the temperature of the solution for pH temperature
compensation. Only active when temperature sensor is unplugged. See
section 5.3.
