Elite Series CPL290 Measurement Ranges and Probes

Probe Sensing Area

The probe sensing area determines the probe's measurement range.

Larger Sensing Area = Larger Range

Sensing areas are indicated with a letter designation and are combined with the probe body style to form a probe model number such as C23-C (C23 body style and C size sensing area).

Target area diameter must be 130% of the sensing area diameter or custom calibration will be required.

Calibration Types

Four different calibration types are available enabling you to find the optimal pairing of range and resolution. While resolution as a percent of range is very similar, the smaller ranges have correspondingly smaller resolution values. Not all probes are available in all calibration types.

CPL290 dual range/sensitivity typically uses one probe calibrated to two different calibration types.

Ultrafine	Smallest resolution
Fine
Standard
Extended	Largest range

* For other bandwidths use 100 Hz values with these multipliers: 1 kHz-1.4, 10kHz-1.8, 15 kHz- 2.0 (15 kHz is standard/unfiltered)
Resolution values are RMS. Peak-to-peak values are typically ten times greater than the RMS values.
In high EMI conditions (10 V/m), output DC level may shift and noise may rise to 0.2 VRMS (1% resolution)
**10 kHz maximum bandwidth for these sensing areas.
