2. Numerical value of the current measurement
3. Graphic (min, max, value, ve-second rolling range)
The number on the left side of the graphic’s linear scale is the minimum value of the range (e.g. 0.000 V).
The number on the right side of the graphic’s linear scale is the maximum value of the range (e.g. 400.0 mV).
The gray bar shows the ve second rolling average of measurements.
The inverted triangle shows the location on the scale of the current measurement value.
4. Minimum measurement value recorded since you powered on the instrument or since y ou last pushed the Reset
DVM Sta
tistics menu item.

6. Average of all measurement values re corded since you powered on the instrument or since you last pushed the Reset
DVM Statistics menu item.
7. Frequency
NOTE
. A n “Over bandwidth” message appears for voltage measurements 10 kHz. An “Under bandwidth” m essage
appears for voltage measurements 10 Hz. A “?” message appears next to m in or max measurements that have gone
out of bounds. Push Reset DVM Statistics to remove the “?” from the display.
