Preparing for Current Measurements
• Turn off circuit power before connecting the Test Probes.
• Allow the meter to cool between measurements, if current measurements
approach or exceeds 10 amps.
• A warning tone sounds if you connect a test lead to a current input while a
current function is not selected.
• Open circuit voltage at the measurement point must not exceed 1000 V.
• Always measure current in series with the load. Never measure current across a
voltage source.
