This meter measure pH, millivolts, relative millivolts and temperature. The instruction manual serves to explain the use of the pH 1100/ 2100 bench meter as a step-by-step operational guide to help you familiarize with the meter's features and functions. [. . . ] 4. 5. Mode 31 Instruction Manual pH 1100/ 2100 10. 2. 5 pH Measurement Alarm Setup Program P1. 3 Use this program to select alarm for low and high pH measurements. Enter pH/Temperature setup mode as described in steps 1-4 in 10. 2. 1 Entering pH/temperature setup mode (page 30). · · If you selected On continue to step 6 If you select Off, pressing ENTER returns to the setup mode. pH Meas. 4. Off pH Alarm On Select & Press ENTER Figure 88 5. Key In Low Alarm pH Set Point:2 . 000 Figure 89 Press /MI key to continue to the next setup program, or press /MR to go to the previous program. If you selected On, the display now reads Key in Low Alarm pH Set Point. If you make a mistake, use the /MI or /MR keys to highlight mistake, then re-enter. The high alarm must be set at least 1. 0 pH greater than the low alarm. If you make a mistake, use the /MI or /MR keys to highlight mistake, then re-enter. Press ENTER to confirm high pH set point value and return to the setup mode. Press /MI key to continue to the next setup program, or press /MR to go to the previous program. Press EXIT to return to the pH measurement mode.

[. . . ] Temperature changes also affect the signal the pH electrode sends to the meter and causes a loss of accuracy for the reading. To limit the loss of accuracy during calibration, make the temperature of the pH buffer calibrating solutions and the sample solution the same. 13. 2 pH Buffer Calibration Solution You can use standard buffer solutions to calibrate a pH meter before you measure the pH of a sample. Calibration solutions serve as basis of comparison between measurements. For 1-point calibration, use a standard buffer of pH 7. 00 or 6. 86, or a standard or custom buffer whose pH value is close to that of the sample. [. . . ]
