The pH sensor can be easily replaced in the field. The Model 63 has a non-detachable cable available in lengths of 10, 25, 50 or 100 feet (3, 7.6, 15.2 or 30.5 meters). The probe body has been manufactured with stainless steel to add rugged durability and sinking weight.
YSI Model 63 should ever need repair. Batteries There are a few things you must do to prepare your YSI Model 63 for use. First, locate the six AA-size alkaline batteries and the battery cover kit which were included. Then locate the markings inside each of the two battery-chamber sleeves that illustrate the correct way to install the batteries.
Insert the round sponge (provided with the Model 63) into the bottom of the chamber. Put 6-8 drops of tap water into the sponge. The wet sponge creates a humid environment for the pH sensor to prevent it from drying out during transport in the field (up to one week).
Preparing the Probe The YSI Model 63 is shipped without the pH sensor installed. The pH sensor must be installed before using the system (see section 3.1 Installing the pH Sensor, below). The sensor is shipped with a protective bottle filled with a mixture of pH 4 buffer and KCl solution. Do not remove the bottle until you are ready to use the instrument.
The user can choose from two sets of pH buffer values for 3-point calibration. The first set consists of the standard YSI pH buffer values of pH 7 (YSI 3822), pH 4 (YSI 3821) and pH 10 (YSI 3823). The second set available is the NIST pH 6.86, 4.01 and 9.18. Note that the first calibration point must be either pH 7 or pH 6.86.

4. To enter the calibration menu, use two fingers to press and release both the UP ARROW and DOWN ARROW keys at the same time. The Model 63 display will show CAL at the bottom, STAND will be flashing and the pH reading will show 7.00 (the buffer to be used to adjust the offset).

6. When the reading is stable (does not change by 0.01 pH in 10 seconds), the decimal point will stop flashing. Press and hold the ENTER key to save the calibration point. The Model 63 will flash SAVE on the display along with OFS to indicate that the offset value has been saved.

11. When the reading is stable (does not change by 0.01 pH in 10 seconds), the decimal point will stop flashing. Press and hold the ENTER key to save the first SLOPE. The Model 63 will flash SAVE on the display along with SLP to indicate that the first slope value has been saved.

7, the third buffer must be greater than pH 7. 16. Press the ENTER key. The Model 63 display will now show CAL at the bottom, SLOPE will stop flashing and the pH calibration value (automatically sensed by the instrument) is shown with one of the decimal points flashing.
• For fresh water choose a 1 mS/cm conductivity standard (YSI Catalog# 3167) • For brackish water choose a 10 mS/cm conductivity standard (YSI Catalog # 3168) 3. Place at least 7 inches of solution in the plastic container (provided with the Model 63) or a clean glass beaker.
ENTER key. The word “SAVE” will flash across the display for a second indicating that the calibration has been accepted. The YSI Model 63 is designed to retain its last conductivity calibration permanently. Therefore, there is no need to calibrate the instrument after battery changes or power down.

Temperature °C NOTE: When the Model 63 is turned off, it will “remember” which mode you used last and will return to that mode the next time it is turned on. If turned off while in recall or erase mode, it will default to pH mode when turned on.
(within the specifications of the instrument) all you need to do to get the most accurate reading is to put the probe in the sample. This feature makes the Model 63 as simple as possible to operate.
ID number in the lower right corner. Site identity 2. Press the ENTER key to review the last set of data that was saved. The Model 63 will display the pH and temperature. Another press of the ENTER key will display the conductivity and the temperature.
7. When you have finished recalling data, press MODE two times to return to normal operation. NOTE: The Model 63 will recall data as a list. When the UP ARROW is pressed the Model 63 will display the Site ID# for the previously recorded data. For example: If you are reviewing Site ID# 5 and the UP ARROW is pressed, the Model 63 will display Site ID#4.
Display Backlight At times it may be necessary to take measurements with the Model 63 in dark or poorly lit areas. To help in this situation, the Model 63 comes equipped with a backlight which will illuminate the display so that it can be easily read. To activate the backlight, press and hold the LIGHT key.
For that reason, we have made the YSI Model 63 flexible to accommodate these “advanced users.” If, for example, you are using the YSI Model 63 for a process control application which requires that the conductivity readings be compensated to 20...
Changing Conductivity From Autoranging To Manual Ranging If your application is easier to perform using a manual range which you select, the YSI Model 63 allows you to turn off the default autoranging feature. While you are making conductivity or temperature compensated conductivity measurements, simply press and release the UP ARROW key.
Maintenance pH Sensor Precautions 1. When making measurements or performing the calibration procedure, make certain that the level of sample or pH buffer is high enough to cover both the pH and temperature sensors. 2. Rinse the probe with deionized water between changes of calibration buffer solutions. 3.
pH Sensor Storage For short term storage between measurements in the field (up to one week), place the probe in the transport chamber in the side of the instrument case. Make sure that the sponge inside the chamber is wet (tap water). For long term storage (over one week), place the probe in the storage bottle (provided) containing a mixture of 50% pH 4 buffer and 50% 1.5M KCl.
Performing a calibration will eliminate any error which might arise because of cell constant change. YSI cells are calibrated to within one percent of the stated cell constant at a single point. We consider these products to be usefully linear over most instrument ranges. The cell constant can...

Temperature Error = ± 1% maximum The solution temperature error is the product of the temperature coefficient and the temperature offset from 25°C, expressed as a percentage of the reading that would have been obtained at 25°C. The error is not necessarily a linear function of temperature. The statement of error is derived from a 25°C temperature offset and a 3%/°C temperature coefficient.

Number of pH Calibration Points When calibrating the YSI Model 63, you have the choice of 1-point 2-point, or 3-point calibration. Perform a 2 or 3 point calibration at least once per day for accurate results.
