4 Press the Lower softkey; then, turn the Entry knob to set the lower measurement
threshold value.
Increasing the lower value beyond the set middle value will automatically
increase the middle value to be more than the lower value. The default lower
threshold is 10% or 800 mV.
If threshold Type is set to %, the lower threshold value can be set from 5% to
93%.
5 Press the Middle softkey; then, turn the Entry knob to set the middle
measurement threshold value.
The middle value is bounded by the values set for lower and upper thresholds.
The default middle threshold is 50% or 1.20 V.
• If threshold Type is set to %, the middle threshold value can be set from 6% to
94%.
6 Press the Upper softkey; then, turn the Entry knob to set the upper
measurement threshold value.
Decreasing the upper value below the set middle value will automatically
decrease the middle value to be less than the upper value. The default upper
threshold is 90% or 1.50 V.
• If threshold Type is set to %, the upper threshold value can be set from 7% to
95%.
