1550B Users Manual Note Individual test locations cannot be deleted, however, they can be overwritten. W Caution The delete function deletes all of your stored test results. Maintaining the Meter XW Warning To avoid possible electric shock or personal injury, do not attempt to repair or service your Meter beyond what is described in this manual. Only qualified service personnel should service the product. There are no user-replaceable parts inside the Meter. Cleaning XW Warning To avoid possible electric shock or personal injury, remove excess water from the cloth before cleaning the Meter to ensure that water does not enter any terminal. Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents to clean the Meter. Principle of Measurement and Resistance The Meter measures insulation parameters and displays the results using with the following formulas. Ohm's Law R=V I Capacitance (charge) C=Q V PI (Polarization Index) PI = R × 10 min R × 1 min DAR (Dielectric absorption ratio) DAR = R × 1 min R × 30 s 20
