functions
Press the SELECT button momentarily to select the subject functions in sequence. Last
selection will be saved as power up default for repeat measurement convenience.
Note: Hz Input sensitivity varies automatically with voltage (current function alike) range
selected. 5V range has the highest and the 1000V range has the lowest. Auto-ranging
measurements normally set the most appropriate trigger level. You can also press the
RANGE
button momentarily to select another trigger level (voltage range) manually. If the
Hz reading becomes unstable, select higher voltage range to avoid electrical noise. If the
reading shows zero, select lower voltage range for better sensitivity.
Note: In
dBm
+Hz
function, power up default reference impedance will be displayed for 1
second before displaying the dBm readings. Press
dBm-

select different reference impedance of 4, 8, 16, 32, 50, 75, 93, 110, 125, 135, 150, 200,
250, 300, 500, 600, 800, 900, 1000, up to 1200
. Last selection will be saved as power up
default for repeat measurement convenience. Manual trigger level selection on Hz reading
is not available in this function.
