You can correct gaps between measured values and nominal values of the standard solutions, which resulting from shifts of the comparison electrode or contamination on the metal surface of the electrode. HINT! Tapping on the ORP CAL screen allows you to check the current calibration data.
Chapter 6 ORP Measurement 6.2 ORP Measurement Setting This section describes the procedures to set the conditions of ORP measurement. 1. Tap the channel setting and the measurement item in the MEAS screen to set "CH1" and "ORP". 2. Tap and tap "CH1 MEAS SET". 3. ORP measurement setting items are displayed. When setting item increased, you will see the remaining items by dragging. 4. Select items and set the conditions. The setting procedures for each item are explained below. 6.
Chapter 6 ORP Measurement 6.4 Alarm Setting When the measurement values exceeds the set upper or lower limit, the instrument detects it to display the notice on the screen or to output the signal from the external ouput terminal. If the measurement values exceeds the alarm range, the color of the pertinent channel "CH" is changes on the MEAS screen. Set the upper limit alarm to ON for the upper limit control of measurement value.

Chapter 6 ORP Measurement 6.7 ORP Measurement This section describes the procedures of ORP measurement. 1. Wash the electrode with pure water (ion exchange water), and wipe it off either with filter paper or tissue paper. 2. Open the internal solution filler port of the electrode. During measurement, the filler port should be kept open. The filler port configuration depends on the electrode type. 3. Immerse the electrode into the sample solution deeper than 3 cm from the tip.
Chapter 7 Application Mode Chapter 7 Application Mode The application mode enables the measurement for the ION standard addition method and the pharmaceutical water inspection methods under various Pharmacopeias by conductivity measurement in conformance to specific measurement methods. By simply submerging the electrode to a sample, the instrument will walk you through the process and will determine the result.
Chapter 7 Application Mode Sample addition method (Single) The sample is added only once to the standard solution of the target ion species. Sample addition method (Double) The sample is added twice to the standard solution of the target ion species. This mode is used to obtain the electric potential slope of the electrode used. 7.1.3 General Cautions for Standard Addition Method In order to obtain more accurate and reliable data, pay attention to the following points.
Chapter 7 Application Mode 7.1.5 Known Addition Method (Single) Measurement In the known addition method (Single), the targeted ion concentration in a sample solution is obtained from a change in electric potential by adding once a small amount of the target ion solution to the sample solution. Measurement condition setting 1. Tap on the right of the known addition method item in the ION standard addition mode screen. 2. Tap on the right of the Known add. method (Single) item. 3.
Chapter 7 Application Mode 7. Immerse the ion electrode in sample solution after the additive standard solution and tap . The measurement starts. When the measurement is completed, concentration of the sample and the measuring condition are displayed as measurement results. Tap to return to the ION standard addition mode screen. 7.1.
Chapter 7 Application Mode HINT! For more accurate measurement: Normally, the amount of the standard solution to be added should be from 0.1% to 10% of the sample solution. It is desirable that when the standard solution is added to the sample solution, the concentration of the ion species under measurement increase by 1 to 10 times in the sample solution.
Chapter 7 Application Mode 3. Set the measurement condition in the Sample add. method (Single) screen. Enter sample volume, concentration of the additive standard solution, volume of the additive standard solution and electrode slope. 4. Tap key after complete setting. The MEAS screen is displayed. To return the set value to default, tap the Setting item and range Volume of the additive sample solution: Electrode slope: Concentration of the standard solution: Standard solution volume: . 0.01 mL to 1000.
Chapter 7 Application Mode 3. Set the measurement condition in the Sample add. method (Double) screen. Enter the 1 and 2 volume of the additive sample, concentration of the standard solution, volume of the standard solution and ion valency of measurement ion. 4. Tap after complete setting. The MEAS screen is displayed. To return the set value to default, tap the Setting item and range Volume of the additive sample 1, 2: Ion valency: Concentration of the standard solution: Standard solution volume: . 0.
Chapter 8 Periodic Inspection Mode Chapter 8 Periodic Inspection Mode This chapter explains about the function to periodically check performance of the instrument and the electrode in pH, ION, and COND measurements using. We recommend that you perform the check once every 3 months. Setting conditions are described individually in each pH, ION, and COND measurement item. 8.
Chapter 8 Periodic Inspection Mode 8.1.2 JIS Mode According to JIS regulation, the measurement with a solution of pH9 is given three times after measurement by standard solutions of pH7 and pH4. The result is displayed on the screen. When the periodic inspection mode starts, the operation guide is shown on the screen. Perform measurement by the standard solutions in the following order. (1) pH6.865 (2) pH4.008 (3) pH9.180 (4) pH9.180 (5) pH9.180 1.
Chapter 8 Periodic Inspection Mode (6) Repeatability The repeatability shows the difference between maximum and minimum of the indication given by three times of measurements using the standard solution of pH9 (see the values (3), (4), and (5) above). OK (0) Within ±0.005 pH Equivalent to 0 in JIS OK (1) Within ±0.02 pH Equivalent to I in JIS OK (2) Within ±0.05 pH Equivalent to II in JIS NG Over ±0.05 pH - (7) Linearity Regulation (Within ±0.03 pH) This is equivalent to "0" and "I" in JIS.
Chapter 8 Periodic Inspection Mode 8.1.3 Pharmacopoeia Mode After measurement with the standard solutions of pH7 and pH4 (or pH9), the measurement using the standard solution of pH7 is repeated 5 times, and the result is displayed.
