are trapped. Connect the probe to the meter enter USP mode and press the
Stage 1 key. The instrument will perform a temperature and conductivity
measurement (using a non-temperature corrected conductivity reading).
• Using the Stage 1 temperature and conductivity requirement table the
corresponding conductivity limit at that temperature is determined.
• If the measured conductivity is no greater than the table value the water
meets the requirements of the test for conductivity. If the conductivity is
higher than the table value, proceed with stage 2.
