9. Technical data
9.1 Features
The Field Verification Device
• determines if the ModMAG
®
M2000 or B-MAG I M5000 is within one percent of the
original factory calibration.
• verifies the functionality of all of the meter’s inputs and outputs.
• measures electrode resistance and integrity.
• measures coil resistance and integrity.
• measures coil insulation resistance.
• measures current and frequency at previously selected flow rate.
• evaluates the signal processing functionality.
• verifies that there is no high-voltage noise disturbing the coil circuit.
• provides certified printout showing test results.
• is capable to store 100 meter tests.
