1 INTRODUCTION
The RST VW2106 Readout is a lightweight device used to read and display vibrating
wire sensor and thermistor data. It is suitable for harsh environments and the user
interface is simple to use.
The VW2106 readout is powered by 3 standard "AA" alkaline batteries to facilitate
replacement in the field. Data can be reviewed either on-board or downloaded to the
computer using RST-provided software.

The latest model of the VW2106 features push post terminals to easily connect VW
Sensor instruments, visual instructions for using the terminal posts and changing the
batteries (Figure 1-2), and a refreshed look.
FIGURE 1-2 VISUAL INSTRUCTIONS FOR TERMINAL POSTS AND BATTERY CHANGES
If you have an older model VW2106, please refer to Section 3.2 for instructions to
connect a single field instrument to the readout. The multi-channel connection
instructions are identical for all models.

This product is battery operated. There are no major safety concerns associated
with use.
It is important to keep the unit clean during use in the field. Ensure there is no dirt or
dust in the wire terminals, battery compartment, and weather seal along the edge of
the lid of the enclosure. Make sure that weather caps for the USB port and
expansion port are properly secured when not in use.

CAUTION: MAKE SURE THAT THE WIRES ARE CLEAN AND FREE OF DIRT BEFORE
INSERTING THEM INTO THE TERMINALS.
CAUTION: ENSURE THAT CABLES HAVE ENOUGH SLACK TO FACILITATE
ATTACHMENT.APPROXIMATELY 2” OF SLACK IS RECOMMENDED.
CAUTION: ENSURE THAT THE TERMINALS ARE FREE FROM DIRT AND DEBRIS
BEFORE INSERTING THE WIRES.TERMINALS CAN BE BLOWN OUT WITH COMPRESSED
AIR IF NECESSARY.
2. Firmly press down on the first terminal post (Figure 3-2).
