Electrode Connections 1. Remove BNC shorting cap. 2. Attach electrode with BNC connector by sliding BNC connector onto electrode input (1), then push down and turn clockwise to lock into position. NOTE: If using a combination electrode with a BNC connector, the reference electrode input (2) is not used. 3. Attach ATC probe with DIN connector by sliding the DIN connectors into the ATC probe input (3) until firmly in place. pH Measurement Overview pH measurement is easy and accurate with the Orion 720Aplus. The meter/electrode system is calibrated with one to five buffers which bracket your sample pH. For better accuracy, at least a two buffer calibration is recommended. The autocalibration feature automatically recognizes 1.68, 4.01, 7.00, 10.01, and 12.46 buffers. For best results, an ATC probe is recommended to compensate for temperature variation. ISE Measurement Overview Direct measurement using ion selective electrodes (ISE’s) is fast and convenient with the Orion 720Aplus. The meter/electrode system is calibrated with one to five standards of known concentration which bracket sample concentration. Unknown sample concentration is then read directly from the display in units used for calibration molarity, ppm, %, etc. Rec. Gnd. ATC/DIN KF Input 1 Ref.1 Input 2 Ref. 2 3 1 2 BNC Shorting Cap Quick Start Guide Orion 720Aplus pH/ISE Meter All meter functions are described in detail in the accompanying instruction manual. For calibration and measurement only a few steps are required. Step-by-step instructions are given in this guide. Meter Overview 1. Results and current mode are displayed in the large main field. 2.
