5. Read the forward voltage drop on the digital display:
5.1
A good silicon diode will result in a reading around
0.7 V.
5.2
A good germanium diode will result in a reading
around 0.3 V.
5.3
A short is indicated by a continuous beep and a
reading of .000 V.
5.4
An open is indicated by a 1. V reading.
6. Reverse the test probe connections to the diode and per-
form a reverse-leakage test of the diode.
6.1
A reading of 1. V indicates reverse blocking and a
good diode.
6.2
A reading of .000 V and a continuous beep indicates
high reverse leakage current or a short.

To Measure AC Current:
Current is measured in amps.
Do not attempt to measure current in circuits capable of deliv-
ering greater than 600V.  If the current is unknown, begin at the
highest range, selecting the next lowest until a reading is dis-
played.
To Measure AC Current (cont.):
1. Connect the test leads into the meter inputs as indicated in
the following diagram.
2. Select the proper range to be used within the AAC area.
3. Turn the power off.
4. Connect the meter in series with the load or circuit.
5. Turn power on.
6. Measure AC Current.
Meter Setup:
Current <200mA AC
Current AMPS>200mA AC
10 Amps Max.
