automated with the standard resistor input terminals connected to the Line A 'Rs C & P'
output terminals of an optional model 16 Channel Scanner(s). These terminals are located
on the front panel for bench top models.
2.3.2. Resistor Under Test Input Terminals (Bench Model Only)
The resistor under test input terminals consist of 4 low thermal binding posts. The binding
posts have the '
Rx ' label above the group of four posts. The posts are labeled clockwise
from bottom left to right, 'C1', 'P1', 'P2', and 'C2'. These posts provide direct connection for
your resistor under test. Switching between multiple resistances can be simplified and
automated with the standard resistor input terminals connected to the Line B 'Rs C & P'
output terminals of an optional model 16 Channel Scanner(s). These terminals are located
on the front panel for bench top models.
2.3.3. Guard Terminal (Bench Model Only)
The guard terminal consists of a four way white binding post. The guard is an active circuit
referenced to the signal low, C1, side of the four terminal Rx resistor. This terminal is
located on the front panel for bench top models. Guard should never be connected to
Ground as this will cause damage to the 6622T. The active guard on the 6622T should
also never be connected to another device's guard that has an active guard such as a Fluke
5700A calibrator or damage may occur. This terminal is located on the front panel for
bench top models.
2.3.4. Circuit Common Terminal (Bench Model Only)
The circuit common terminal consists of a four way black binding post. The circuit
common terminal is connected to the circuit common internal to the model 6622T and is
isolated from the chassis ground terminal. This terminal is located on the front panel for
bench top models. This terminal is typically not used in measurement practice and is
mainly used for diagnostics. This terminal is located on the front panel for bench top
models.
2.3.5. Power
The power-on indicator is lighted when the AC power is applied to the unit and the
power switch on the rear panel is “ON”.
