The Meter can be switched off by pressing and holding down the ON/OFF button for 3 seconds. If the Meter is not used for several minutes then it will switch itself off in order to preserve battery life. Always rinse the probes with fresh water and dry before and after every test. Soak the probes in a cup of fresh water for 15 to 30 minutes before replacing the protective cap and storing.
