Remote tare connection with a momentary switch
The DIP switches are located at the S1 position (Refer to Figure 3-2). Use a small instrument such as a paper clip
to change the switches from open to closed. Table 2-3 lists DIP switch settings at the S1 position required to
complete the setup of your meter.
