Making Measurements

Verify Instrument Operation

Before attempting to make a measurement, verify that the instrument is operational
and the battery is good. If the instrument is not operational, have it repaired before
attempting to make a measurement.

Range Selection

In addition to autoranging (Models 15XP-A and 35XP-A only) you can manually
select and lock a range by pressing the RANGE button. RANGE appears on the
display to indicate that manual ranging is active and the range is locked. When
appropriate, each subsequent press of the range button steps the meter to the next
higher range. When the highest range is reached the next press returns the meter
to the lowest range. To return to autoranging press the RANGE button. If RANGE
still shows on the display, autoranging is not available for the selected function.
Use autorange for all initial measurements. Then, when appropriate, use the RANGE
button to select and lock a range.
To avoid electrical shock while manual ranging, use the display
annunciators to identify the actual range selected.

Correcting an Overload (0o or -0o) Indication W

An 0o or -0o indication may appear on the display to indicate that an overload
condition exists. For voltage and current measurements, an overload should be
immediately corrected by selecting a higher range. If the highest range setting does
not eliminate the overload, interrupt the measurement until the problem is identified
and eliminated. The 0o indication is normal for some functions; for example,
resistance, continuity, and diode test.
Measuring DC Voltage
1. Set the Function Switch to v.
2. Select the desired RANGE. The default DC voltage range is 2 V on the 15XP-A
and 4 V on the 35XP-A.
3. Connect the test leads: Red to E, 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.
