Check Baratron Zero
Note: Allow at least 3 – 4 hours warm-up time for the Baratron to settle before moving on
With the UDV fully closed, your meter should read zero volts. If it does not, then the Baratron must be
zeroed which can be done at the fine adjustment point shown below.
If a zero cannot be achieved with the fine
adjustment, there is a coarse adjustment on the
side of the gauge.
