Cursor 1 only – Single cursor in the display and a single CRSR1 data line below the plot.
Cursor 2 only – Single cursor in the display and a single CRSR 2data line below the plot.
Cursor 1 & 2 active – Dual cursors in the display and two data lines below the plot. Top
data line will indicate the last cursor key pressed (active cursor), display
that cursor’s data, and is under control of the
◄► keys. The second data
line will be the difference in distance and impedance from the opposite
cursor. Both LED’s will be lit. To change cursor control press the cursor
key desired to be active.
NOTE: When the differential reading from the active cursor is from the left to the right the
differential readings will be positive. When the differential reading from the active cursor is right to
left, the differential readings will be negative.
Tone Key – This key activates tones for either coax or twisted pair cables based on
INPUT CHANNEL selection in the METER menu. Use standard twisted pair or coaxial cable
inductive amplifiers (probes) to detect the tones on the cable.
NOTE: Toning works ONLY when operating on batteries. When the AC adapter is connected
some AC is induced with the tones and tones are weakened making them unusable.
