    With Pocket Internet Explorer and a connection to the Internet, you can view Web sites on your XL15 meter by typing an address or Universal Resource Locator (URL) in the Address bar. Web sites that use HTML 4.0, DHTML, animated GIF images, and Java applets may not work correctly in Pocket Internet Explorer without additional software.

  • Page 17: Choosing A Channel

    Choosing a CHANNEL Using the Meter The XL15 is a multi-channel meter. With this meter you can switch from channel 1 to channel 3. You cannot view both channels at the same time. The setup parameters for each screen are independent from one another.

  • Page 18: Button Functions

    BUTTON FUNCTIONS Using the Meter The touch screen of your XL15 bench meter has “buttons” along the right side of the screen that are common to many of the screens. The following indicates the function of these common buttons. The Standardize button accesses the standardization screen from the various measure modes and initiates standardization of the meter once the standardization screen is accessed.

You can manually enter an alphanumeric identification number of 10 characters for any sample or you can have the meter sequentially number your samples beginning at the number of your choice.

  • Page 23: Select Buffer Group

    Select BUFFER GROUP pH Setup This setup option allows you to select from 3 different buffer groups, for auto buffer recognition. Or you can create a custom group of buffers for auto buffer recognition by touching custom. The 3 existing buffer groups are : 2.00 4.00 7.00 10.00 12.00...

  • Page 24: Select Buffer Recognition

    Select BUFFER RECOGNITION pH Setup This option allows you to select Automatic buffer recognition or manual buffer recog- nition when standardizing. With the automatic buffer recognition activated, the meter will automatically recognize the buffers from the chosen buffer group and accept them when the meter recognizes the reading as stable.

  • Page 25: Select Auto Read Mode

    Select AUTO READ MODE pH Setup You can use this meter when the Auto Read function is active or when it is inactive.

  • Page 27: Set Default Temperature

    Set DEFAULT TEMPERATURE pH Setup It is a well known fact that pH is a temperature dependent measurement. The factory default setting is 25°C. If you are taking the pH of a solution that is not 25°C and you are not using an Automatic Temperature Compensation (ATC) probe, then you should enter the temperature value of that solution in order to get the correct pH value.

  • Page 28: Set Isopotential Point

    Set ISOPOTENTIAL POINT pH Setup The isopotential point is the millivolt reading for an electrode at which temperature has no effect on the measurement. pH electrodes are constructed so that the isopo- tential point is theoretically zero millivolts. This is very close to a pH of 7. Most pH electrodes do not achieve this value precisely.

  • Page 44 pH Operation In this mode, you will able to measure the pH of a wide variety of samples. Before meas- uring pH, you will need to standardize the meter using buffers with known pH values. It is good practice to standardize the meter frequently using a minimum of two buffers. Using two buffers allows the meter to calculate and display an actual slope for the electrode, and therefore produce more accurate measurements.

    Fisher-supplied power supply must be used. Use of a power sup- ply that is not approved by Fisher Scientific may cause safety hazards and/or cause unit to exceed EMC limits and/or damage unit. When using this meter with a com- puter or printer, a shielded RS232 cable must be used to meet or exceed FCC regu- lations, and comply with CE Mark requirements.

  • Page 59: Determining Isopotential Points Experimentally

    Determining ISOPOTENTIAL POINTS EXPERIMENTALLY Appendix The isopotential point of an electrode system is the point at which electrode potential is unaffected by a change in temperature. The coordinates of this point would be reported as (pX , Eis ). For an ideal system, this point would be coincident with the system’s Zero Potential Point (pX In practical systems, however, this coincidence rarely occurs, and for some systems, there is no true Isopotential Point but a general Isopotential area.
