Myron L RE-10 Range Extender

The RE-10 Range Extender is a useful accessory for testing high conductivity solutions beyond the normal range of your EP meter. Inserting the RE-10 into a sample-filled cell cup increases the maximum range ten times. Use the Range Extender whenever the reading is off the scale.

Using the RE-10:

• Fill the cell cup three times to rinse it, but each time insert the Range Extender to rinse it also.
• Fill the cell cup with your sample. Push the Range Extender into the cell cup, seating the O-ring seal.
• Use and read the meter in the normal manner. Multiply the reading by 10.
• For best accuracy, repeat the complete test with a fresh sample.
• When you're done testing, remove the Range Extender. Thoroughly rinse the cell cup and Extender with clean water (preferably distilled or deionized) to eliminate dried salts build-up. This is extremely important when the instrument will be used to test high purity water.

Calibrating the RE-10:

• Calibrate your meter (without RE-10) using Standard Solution number 442-3000 (EP) or KCL-7000 (EP10).
• Fill the cell cup with 442-30,000 high conductivity Standard Solution.
• Insert RE-10 and press the button. Multiply the reading by 10 and compare it with the value on the Standard Solution label. It they are not the same the RE-10 must be recalibrated. NOTE: DO NOT adjust the Calibration Control in your meter.
• Adjust the white insert of the Extender as follows: If the reading is too high - push or tap inward. If the reading is too low - twist or pull outward with pliers. NOTE: Each Range Extender is calibrated to a particular meter. It should be recalibrated if it is to be used with another Myron L ® meter.
