4. Connect the test probes to the circuit test points.
5. Read the display, and, if necessary, correct any
overload ( 0o ) conditions.
Measuring DC Voltage
(See Figure 2)
1. Set the Function Switch to  .
2. Select the desired RANGE. The default AC voltage
range is 2 V on the 15XP-B and 4 V on the 35XP-A.
3. Connect the test leads: Red to V , Black to COM.
4. Connect the test probes to the circuit test points.
5. Read the display, and, if necessary, correct any
overload ( 0o ) conditions.
Preparing for Current Measurements
• Turn off circuit power before connecting the test probes.
• Allow the meter to cool between measurements, if current
measurements approach or exceeds 2 amps.
• A warning tone sounds if you connect a test lead to a
current input while a current function is not selected.
• Open circuit voltage at the measurement point must not
exceed 1000V.
• Always measure current in series with the load. Never
measure current across a voltage source.
Measuring DC Current
(See Figure 3)
1. Set the Function Switch to a current function, μA, mA,
or A.
2. Select the desired RANGE (5XP-A only).
3. Connect the test leads: Red to mA or A, Black to COM.
4. Turn off power to the circuit being measured.
5. Open the test circuit ( X ) to establish
measurement points.
