Making Measurements
Measuring Current 4
4-11
W Caution
To avoid blowing the current input fuse or possibly damaging
the Meter:
• Current measurements between 400 mA and 10 A should be
measured using only the 10 A and LO input connectors.
• BEFORE applying power to the circuit to be measured,
ensure the test leads are correctly connected to the Meter
inputs appropriate for the expected current.
• Exceeding 440 mA on the 400 mA input connector or
exceeding 11 A on the 10 Amp connector will blow the
internal fuse.
Current measurements expecting to be between 400 mA and 10 A are made using the
Input LO and 10A input connectors as shown in Figure 4-5.
