resistor network. If 3 V is applied across the total three 1 k
Ω
resistors and V
sense
is across the first 1 k
Ω
resistor, set V
input
to the 10 V range and V
sense
to the 1 V
range. The ratio measurement is approximately 3.00000. If V
sense
is set to the 1 V range, the ratio
displays overflow, with SENSE HI and SENSE LO terminals exceeding the 125 % maximum
reference to the LO terminals. The SENSE HI to LO is 3 V and SENSE LO to LO is 2 V, respectively.

Do not apply more than 1000 V
peak
to the INPUT terminals or more than 350 V
peak
to the SENSE
terminals. Failure to heed this caution may result in instrument damage.
