Replacing the Batteries

The Elite pH tester uses four AAA 1.5 V batteries.
1. To remove the battery cover, See Figure 1. Clear the front catch and

Getting Started

The Elite pH tester has been factory calibrated and usually works well out of the box. However, after extended
periods of non-use, it is best to ensure that the sensor is hydrated. Fill the cap with electrode storage solution or pH
buffer and soak the sensor as needed to get a stable pH reading. A brief rinse with deionized (DI) water is OK, but
avoid soaking or storing in deionized water as this will shorten pH electrode life. Prior to taking the measurements,
periodic calibration with certified standards is recommended for best accuracy.

Buffer Set Selection

Select either USA (pH 4.01, pH 7.00 and pH 10.01) or NIST (pH 4.01, pH 6.86, and pH 9.18) to match your calibra-
tion standard values.
1. Press to power on.
