I have a YSI 30 SCT meter on the cable is a tag 30-25 01C0549 does that reference the part number and the length of the cable?

100 hours of continuous operation. When batteries need to be replaced, the LCD will display a "LO BAT" message. The YSI Model 30 instrument case is waterproof (rated to IP65). You can operate your Model 30 in a steady rain without damage to the instrument.

Page 7: Section 2 Preparing The Meter
BATTERIES There are a few things you must do to prepare your YSI Model 30 for use. First, locate the six AA- size alkaline batteries that were included. Use a screwdriver or a small coin to remove the thumbscrew on the bottom of the instrument.
Page 8: Storage Chamber
An optional sponge is available from YSI that will fit inside the storage chamber and provide a moist environment for probe storage should your application or operational procedures require it.
Page 9: Section 3 Making Measurements
SECTION 3 MAKING MEASUREMENTS The YSI Model 30 is factory calibrated. This means that once you have put batteries in the instrument, you are ready to begin taking readings immediately. The following diagram is an overview of the operation of the Model 30 and 30M. Note the difference in key strokes between some of the 30 and 30M functions.
Page 10: Measurement Modes
To dislodge any bubbles which might have formed, move or shake the probe vigorously several times before recording the measurement. MEASUREMENT MODES The Model 30 has three modes as follows: ! Conductivity -- A measurement of the conductive material in the liquid sample without regard to temperature...
Page 11: Autoranging & Range Searching
(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 30 as simple as possible to operate.
Page 12: The Backlight
Section 3 THE BACKLIGHT At times it may be necessary to take measurements with the Model 30 in dark or poorly lit areas. To help in this situation, the Model 30 comes equipped with a backlight which will illuminate the display so that it can be easily read.
Page 13: Section 4 Saving Data
This feature is useful in situations where transcribing data is difficult or not available. NOTE: The Model 30 is NOT equipped with memory and cannot save data. SAVING DATA TO MEMORY 1.

Page 17: Section 5 Calibration
BEFORE YOU CALIBRATE IMPORTANT: System calibration is rarely required because of the factory calibration of the YSI Model 30. However, from time to time it is wise to check the system calibration and make adjustments when necessary. Before you calibrate the YSI Model 30, complete the procedures discussed in the Preparing the Meter and Making Measurements sections of this manual.
Page 18 NOTE: If the up or down arrow keys are not pressed during the calibration process, the “SAVE” message will not be displayed since the calibration value has not changed. If an error occurs during calibration, see Section 9, Troubleshooting. YSI, Incorporated Model 30/30M...
Page 19: Section 6 Advanced Setup
For that reason, we have made the YSI Model 30 flexible to accommodate these “advanced users.” If, for example, you are using the YSI Model 30 for a process control application which requires that the conductivity readings be compensated to 20 C instead of 25 C -- this is the section to read.
Page 20: Changing The Reference Temperature
See Appendix C for charts of common salt solutions at various temperatures. CHANGING THE REFERENCE TEMPERATURE Follow these steps to modify the reference temperature of the Model 30. 1. Turn the instrument on and wait for it to complete its self test procedure.
Page 21: Changing From Autoranging To Manual Ranging
CHANGING FROM AUTORANGING TO MANUAL RANGING If your application is easier to perform using a manual range which you select, the YSI Model 30 and Model 30M allow you to turn off the default autoranging feature. Follow the instructions for your model as shown below.
Page 22 Model 30M through the four manual ranges and return the instrument to autoranging. NOTE: You may see an error message in some manual ranges if the manual range selected is not adequate for the sample you are measuring. rErr Range error message 24.8 °C YSI, Incorporated Model 30/30M...
Page 23 If this happens, simply press and release the UP ARROW key until a range is selected which is suitable for your sample. Note that the instrument will always default to autoranging when first turned on. The four ranges of the YSI Model 30 are: Range 1 Range 2...

Page 26: Discussion Of Measurement Errors
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 be calibrated to ±0.35% accuracy with YSI conductivity calibrator solutions.
Page 27 Only trial and error in the actual measurement environment can be suggested as an approach to reduce such errors. If the reading does not change as the setup is adjusted, errors due to such factors can be considered too small to see YSI, Incorporated Model 30/30M...

Page 29: Section 8 Maintenance
You may need to tap the probe gently to dislodge any air bubbles. 3. Ideally, the cell should be at least ¼ inch away from any other object, including the sides or bottom of the solution container. YSI, Incorporated Model 30/30M...
Page 30 The user should determine the effects of these and make the necessary corrections, either by shielding or by disconnecting those units that cause trouble. 7. Always rinse the cell carefully before transferring it from one solution to another. 8. Never store a dirty or contaminated cell. YSI, Incorporated Model 30/30M...
