Application Notes (DC Volts)
The 275 will accurately measure rectified DC Voltages like
those encountered in furnaces and other appliances even
though many of these devices do not have output filtering
or other signal conditioning.
When measuring DC Voltage of a bat-
tery, the most accurate reading can be
attained by testing the battery under
load. To accomplish this, follow steps
1 through 4 shown on page 14 and
the following (with the battery in
holder and device turned on):
• Connect the red test lead from the
• Connect the black test lead to the
meter to the positive (+) terminal
of the battery.
negative (-) terminal of the battery.
