The HI-3001 meter covers 0.5 MHz to 1000 MHz with accuracy within +1 dB v/m over the entire range.

Plain English Summary

Summary written for general audiences

The instrument measures fields from 0.5 MHz to 1000 MHz and from 1 v/m to 3160 v/m in six ranges. Its isotropicity is specified as +1 dB over the full rotation of the probe head. The standard battery pack provides approximately 40 hours of continuous operation.

Why This Matters

The meter can withstand continuous wave signals up to 800% of full scale. LED indicators signal overload and low battery conditions. An audio tone proportional to the reading lets the operator locate high-field regions.
