Mode' for details), when measuring starts, meter will automatically measure, calculate and display
measuring result. In case measuring in accordance with set balance condition, the measuring
finishes! At this time, you can press 'STORE' key to store present measuring result. If it is
connected with TP-16 printer before turning on, meter will print present measuring data by pressing
'PRINT' key.
Press 'X' key on top right corner and then press 'ENTER' to finish the measurement.
4.6.1.1 pH Electrode Calibration
1. Before each measurement, suggest re-calibrate the electrode. When calibration starts, previous
calibration data will be recovered.
2. Electrode should be re-calibrated after a period of using
3. Meter will remind automatically when the electrode calibration time interval is set to suitable
value.
Under pH measuring mode, press 'STD' key, select 'pH Electrode Calibration' and then press
'ENTER' key or in 'View pH STD Data' mode, press 'STD' key, you can calibrate electrode slope
also. Meter reminds 'Calibrate Electrode?' press 'ENTER' key, meter enters into calibration mode
which is displayed as follows:
On upper half of the screen is current measuring data, meter displays current pH value (slope is set
as 100.00%), potential value and temperature value. In the middle of the screen is 'Current STD
Buffer Group' set by user. At the bottom is current 'STD Result'. On right side is 'AUTO' (or
'MANU') key, "SETUP' key and END' key.
Automatic distinguish (or manual distinguish) means whether present distinguish mode is
automatic distinguish or manual distinguish, press 'AUTO' (or 'MANU') key, you can switch
between automatic distinguish and manual distinguish quickly. Press 'SETUP' key to set current
STD buffer group. In standard solution, when electrode displaying is stable, press 'ENTER' key to
calibrate present solution, press 'CANCEL' key to quit.
Meter has automatic distinguishing function, can distinguish 10 standard buffer solutions. Because
pH range of 10 standard buffer solutions maybe duplicated, in order to ensure the precision of
measuring result, before measuring, you'd better check the set STD buffer group. For example, you
want to use 4.003pH, 9.182pH STD buffer to calibrate electrode slope, then you can set STD buffer
