MAX/MIN
The "MAX/MIN" function can be used when measuring with voltage,
current, resistance, temperature, and DC μA functions. When the
"MAX/MIN" button
7
is pressed, the meter keeps track of the
Maximum and Minimum values, and the difference between the
Maximum and Minimum values while continuing to take samples.
1. When measuring, press "MAX/MIN" button
7
to toggle between
the Maximum value (MAX), the Minimum value (MIN), and the
difference between Maximum and Minimum (MAX-MIN) values.
" MAX ", " MIN ", or " MAX-MIN " will appear on the display, indicating
the value being shown. If a new maximum or minimum occurs the
display updates with that new value.
2. Press "MAX/MIN" button
7
for more than two seconds to return
to normal measuring mode.

8
again to
exit relative mode.
DC ZERO Function: When measuring DC current with the clamp,
press REL/ZERO to activate the DC current zero function. This will set
the display to zero by subtracting the current value as an offset. The
