Top Tips for successful measurements using optical electrodes¾ Always keep the measurement chamber and electrode lenses clean.¾ Always fit the sleeve and end cap during both calibration and measurement.¾ Ensure the End Cap Plug is also always fitted.¾ Always allow the readings to settle completely during both calibration andmeasurement.¾ Always try to eliminate air bubbles by agitating the Probe after insertionboth during calibration and measurement.¾ Always calibrate and zero the electrode as close to your sample temperatureas possible. This is especially important with the PT 1557 Refined Oil probe.¾ Always zero the optical electrodes just prior to use in clean water (bottledstill mineral water is ideal) then deploy without disturbing themeasurement chamber. This is especially important when using theTurbidity and Refined Oil probes.2.5. About the LanyardThe lanyard supplied with the Macro 900 Meter may, at first, appear to be alittle long. This is intentional. In order to keep the Meter out of the way whilstyour hands are full, the lanyard has been made long enough to wear roundyour neck and over your shoulder so the Meter sits on your hip.The extra length also allows the meter to be held in a comfortable position infront of you during normal use. In order to prevent you being dragged into thewater in the event of the Probe cable becoming snagged, the lanyard includes aquick-release clip.
