PD6100 Strain Gauge, Load Cell, & mV Meter Instruction Manual

Shunt Resistor (Switch 5)
The PD6100 provides a means of simulating strain in a strain gauge bridge circuit via a 60.4KΩ shunt
resistor included in the meter. This will simulate an approximate 70% full-scale load in the case of a 350Ω
strain bridge.
Switch 5
ON
Shunt
Shunt resistor is connected to
the input bridge.
Turn switch ON when you want
to simulate a strain load
OFF Shunt
Shunt resistor is disconnected
from the input bridge.
Turn this switch OFF to remove
the shunt resistor
Strain Gauge Connections
The following figures show examples of strain gauge connections.
There is a 5-position DIP switch (CONFIG) to set up the input ranges and ratiometric operation.
NOTE:
Refer to Switch Configuration starting on page 13 for proper configuration switch
positioning.
