AP015 Current Probe Instruction Manual
Specifications
The following specifications are valid for model AP015 current probes after the probe has reached operating
temperature, which is 20 minutes with power applied in a environment with stable ambient temperature. The
probe must be operating within the environmental conditions listed in the General Characteristics section, and
has been calibrated within the past 12 months in a ambient temperature of 23 ±5

PERFORMANCE VERIFICATION
This procedure can be used to verify the warranted characteristics of the AP015 Current Probe.
The recommended calibration interval for the model AP015 Current Probe is one year. The complete
performance verification procedure should be performed as the first step of annual calibration. Test results can
be recorded on a photocopy of the Test Record provided at the end of this manual.
Performance verification can be completed without removing the instrument covers or exposing the user to
hazardous voltages. Adjustment should only be attempted if a parameter measured in the Performance
Verification Procedure is outside of the specification limits.
Adjustment should only be performed by qualified personnel.
Test Equipment Required
The following table lists the test equipment and accessories, or their equivalents, which are required for
performance verification of the AP015 Current Probe.
Because the input and output connector types may vary on different brands and models of test instruments,
additional adapters or cables may be required.

1. Connect the AP015 to the channel 1 input of the oscilloscope, and completely close the probe
slider.

2. Turn the oscilloscope on and allow at least 30 minutes warm-up time for the AP015 and test
equipment before performing the Verification Procedure.
3. Turn on the other test equipment and allow these to warm up for the time recommended by the
manufacturer.
4. While the instruments are reaching operating temperature, make a photocopy of the Performance
Verification Test Record (located at the end of this manual), and fill in the necessary data.
Functional Check
The functional check will verify the basic operation of all probe functions. It is recommend that the
Fucntional Check be performed prior the Performance Verification Procedure.
1. Select Channel 1 and enter the

coupling menu and verify that the Global BWL is set to OFF.
3. Unlock the slider on the probe by pushing the lever towards the probe cable. Release the lever so
the input slider remains closed, but unlocked.
4. Verify that the message:
Warning: AP015 Probe Unlocked… is displayed on the top of the
screen.
5. Lock the probe slider by pushing fully away from the probe cable.
6. Verify that the warning message dissappears.
7. Degauss the probe by pressing the
DEGAUSS button, (located on the coupling menu), twice.
8. Verify that no error message remains displayed on the top of the screen.
