4. PRECAUTION & PREPARATIONS FOR MEASUREMENTS 1. Remove the power from the circuit when making the measurement. If any voltage is present in the testing circuit, then an erroneous reading will result. 2. Ensure that the batteries (6 x 1.5 V AA battery) is connected correctly the right position into the battery compartment.
5-2 Meg OHM Measurement(Insulation Measurement) * Do not touch the input terminals & the test lead's pins during the measurements. * Do not apply external voltage to input terminals at any time. 1. Connect the RED test plug into "Hi terminal"(3-5, Fig.
1. Connect the RED test plug into "ACV terminal"(3-5, Fig. 1) Connect the BLACK test plug into "COM terminal"(3-5, Fig. 1) 3. Rotate the "Function/Range Switch"(3-2, Fig. 1) to the "600 ACV" position. 4. Connect test alligator clips into circuit under test. Push the "Test Button"(3-4, Fig.
7. BATTERY REPLACEMENT * Remove test leads before open the battery cover ! * Risk of electric shock ! 1. When the upper left corner of LCD display show "BAT". It is necessary to replace the battery. However in-spec measurement may still be made for several hours after LOW BATTERY INDICATOR appears before the instrument becomes inaccurate .
