Description
A INPUT
VZYR HI, LO
Input terminals for Volts, 2-Wire and 4-Wire Ohms, and Hz
measurements. All measurements use the INPUT LO terminal
as a common input. The LO input is isolated and may be
safely floated up to 500 V peak above earth ground regardless
of the measurement type. 1000 V dc is the maximum voltage
rating between the INPUT HI and LO terminals.
