MEASURING CURRENT
The 80i-1000s Current Probe is an optional accessory
designed for use with the ScopeMeter test tool to measure
current flow in electrical circuits. The reading in the
Measure menu can be assigned to current (amps) sensed
by the Current Probe. Refer to the instruction sheet
provided with the 80i-1000s for complete information about
Current Probe operation.
WARNING
TO AVOID ELECTRICAL SHOCK, USE ONLY CURRENT	Figure 7-3.	Current Measurement Setup
PROBE ACCESSORIES SPECIFICALLY DESIGNED	Figure 7-3.	Current Measurement Setup
AND APPROVED FOR USE WITH THE SCOPEMETER
TEST TOOL. OTHER PROBES MAY EXPOSE THE
OPERATOR TO AN ELECTRIC SHOCK HAZARD IF ANY
OF THE THREE COMMON INPUT CONNECTIONS ARE
CONNECTED TO A POTENTIAL GREATER THAN
30V RMS OR 42V DC.

The following example measures the current flow in an electric motor for 220V line power.

Connect the 80i-1000s Current Probe to the red INPUT A

BNC as shown in Figure 7-3.
