attained by testing the battery under
load. To accomplish this, follow steps
1 through 4 shown on page 15 and
the following (with the battery in
holder and device turned on):
• Connect the red test lead from the
meter to the positive (+) terminal
of the battery.
• Connect the black test lead to the
negative (-) terminal of the battery.
• Reconnect power to the circuit and
read the voltage on the 296.
