Testing Battery Voltage (5Xp-A Only) (See Figure 12); Testing Logic Levels (15Xp-B Only) (See Figure 13); Additional Features; Input Test Lead Warning - Amprobe 5XP-A Mode D'emploi

Testing Battery Voltage
1. Set the Function Switch to the appropriate BATT
setting, 1.5 V or 9 V.
2. Connect the test leads: Red to BATT 1.5 V or BATT 9 V,
Black to COM.
3. Connect the test probes across the battery. The meter
applies an appropriate load to the battery.
4. Read the display. A good 1.5 volt battery should
measure >1.2 V, and a good 9 volt battery should
measure > 7.2 V.
Testing Logic Levels
The 15XP-B tests logic levels for TTL logic. The meter displays
plus a ∧ for a high-level (true) condition. The meter beeps
0o
and displays an
See Specifications for the logic 1 and logic 0 voltage limits.
Out-of-limits indications are displayed as
beep occur.
1. Set the Function Switch to LOGIC.
2. Connect the test leads: Red to V , Black to COM.
3. Connect the black lead to logic common.
4. Connect the red lead to the logic test point.
5. Read the display.

ADDITIONAL FEATURES

Input Test Lead Warning

The meter emits a continuous tone when a test lead is
placed in the mA or A input jack and the Function/Range
Switch is not set to a correct current position. (If the meter
is connected to a voltage source with leads connected for
current, very high current could result). All current ranges are
protected by fast acting fuses.
