b. Preliminary Starting Procedure. Before us-
ing the TS-352B/U, carefully read the operating
instructions (para 2-4 through 2-7). For maxi-
mum accuracy in all measurements, use the range
that will produce a meter indication as close to
midscale as possible.
When measuring unknown voltage or
current values, start at the highest
range and reduce the range a step at a
time until midscale deflection is ob-
tained on the meter. Excessive voltage
or current values that cause greater
that full scale deflection can damage the
Before using the TS-352B/U, check the
mechanical zero of the meter. If the
meter pointer is not exactly over the
zero line, reset by using the proper size
