Threshold: Can be set to -5 V to +5 V with 0.1 V setting resolution when the
BNC input is selected. Default is 0.0 V.
Input path: Use to select the frequency counter input path. The choices are:
(Rear BNC): When you use the Rear BNC input, the minimum frequency
for any given gate time is four times higher than expected. For example, a 1 s
gate time has a minimum frequency measurement of 4 Hz.
(ACV Signal): Uses the V INPUT HI and LO terminals.
(ACI Signal): Uses the A INPUT HI and LO terminals. Selecting
(ACV Signal) or (ACI Signal) changes the main Frequency screen to that
shown below. This screen has an additional softkey, (Range). There is no
autorange for ACV and ACI signals. Only discrete voltage or current ranges can
be selected. The available ACV ranges are 10 mV, 100 mV, 1 V, 10 V, 100 V and
1 kV. The available ACI ranges are Auto, 10 μA, 100 μA, 1 mA, 10 mA, 100 mA,
1 A, 10 A, and 30 A. See the screen below.
