Continuity Test; Capacitance Measurement - Amprobe CR50A User Manual

Continuity Test

The Continuity test checks electrical continuity
between two contact points.
1. Set the Function/Range switch to d � .
2. Plug the black test lead into the –Rx jack
(black) and connect the test lead tip to one of
the contact points
3. Plug the red test lead into the +Rx jack (red)
and connect its test lead point to the other
contact point. (See Figure 1 for connections)
4. The internal beeper emits a tone when
resistance is less than approx. 40Ω

Capacitance Measurement

Discharge all voltage from the capacitor (via a
100kΩ resistor) before measuring its value
1. Connect the red test lead to the Cx+ input
and the black test lead to the Cx– input.
2. Set the function/range switch to the
capacitance range that gives the best
resolution.
3. Apply probe tips to the capacitor leads.
When measuring electrolytic capacitors,
observe correct polarity.
4. Read the capacitance value on the display
(you may have to wait a few seconds until
the capacitor is fully charged). If "OL"
appears in the highest range, the capacitor
is too large to be measured.
Note: For small value measurements utilize
