Helios PD2-6100 Strain Gauge, Load Cell, and mV Meter
Shunt Resistor (Switch 5)
The PD2-6100 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.
Shunt resistor is
disconnected
OFF Shunt
from the input
bridge.
Shunt resistor is
connected to the
ON Shunt
input bridge.
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 sensor excitation.
Note: Refer to Switch Configuration on page 17 for
proper configuration switch positioning.
Figure 13. Strain Gauge Powered by Internal
Supply
Figure 14. Strain Gauge Powered by External
Supply
When connecting multiple strain gauges to the meter,
each must be wired in parallel. This is typically done
with the use of a junction box.
Turn this switch
OFF to remove the
shunt resistor
Turn switch ON
when you want to
simulate a strain
load
