Capacitance & Inductance Measurements
1. Set the Function/Range switch to the desired F (capacitance) or H(inductance)
range.
2. Never apply an external voltage to the Cx Lx sockets. Damage to the meter
may result.
3. Insert the capacitor or inductance leads directly into the Cx Lx socket.
4. Read the capacitance or inductance directly from the display.
Frequency Measurements
1. Set the Function/Range switch to the KHz position.
2. Connect the red test lead to the "VW " jack and the black test lead to the
"COM" jack.
3. Connect the test leads to the point of measurement and read the frequency
from the display.
Logic Measurements
1. Set the Function/Range switch to the LOGIC position.
2. Connect the red test lead to the "VW " jack and the black test lead to the
"COM" jack.
3. Connect the red test lead to the test point and the black lead to the common
buss of the logic circuit.
4. A " "on the display indicates TTL logic high and a "
logic low. Both indicators are on when the point of measurement is toggling
high and low.
