6.15.2 FLEX Clamp Adaptor Current and Frequency Measurements
Connect a FLIR Flex Clamp Adaptor (Model TA72 or TA74, for example) or other
clamp adaptor to the DM166 to display current measurements as detailed below:
1. Turn the function dial to the
position.
2. Connect a Clamp adaptor as shown in Fig. 6-10.
3. Set the Range of the Flex Clamp Adaptor to match the range of the DM166.
4. Short press the RANGE button to select the range of the DM166 (1, 10, or 100
mv/A, as shown in the upper left corner of the DM166 display).
5. Operate the Flex Clamp meter (or other clamp adaptor) per the instructions
provided with the Flex Clamp meter or other adaptor.
6. Read the current measured by the Flex Clamp on the DM166 LCD. If ‘OL’
appears, the signal being measured is out of the range of the meter’s
capability. In this case, stop the test immediately and review the application.
7. Short press the HOLD button to freeze/unfreeze the displayed reading.
8. To see the frequency value for the measured current, long press the Hz
button. Long press the button to return to the current measurement display.
