Holaday HI-3001 Broadband Exposure Meter
Holaday HI-3001 Electric Field Meter
The Holaday HI-3001 Electric Field Meter is part of the Holaday HI-3000 series. The HI-3001 has a wider dynamic range of E field measurements. Our unit includes the meter, 3 probes, charger, case, and other items pictured. The GRE and STE probes are standard with the HI-3001. They measure 0.5 MHz to 5 GHz, 2 db. The CH probe is optional, but is included in our kit.
Here is information from the user manual:
"An electric field meter having a wider dynamic range. The GRE and STE electric field probes, standard with this unit, provide measuring capabilities from as low as 10 V2/m2 to 107 V2/m2, or 60 dB range. It is possible to add either the CH Magnetic Field probe or the HSE High Sensitivity Electric Field probe to the HI-3001 as an option.
The HI-3001 is a broadband electric field strength meter. With two electric field probes, it provides a wide dynamic range of E field measurements. It is especially useful for measurements above 300 MHz where magnetic field measurements are not generally necessary. An auxiliary range is available for the addition of an accessory probe. The accessory probe may be either the HSE high sensitivity electric field probe or the CH magnetic field probe. The meter scale is calibrated in field strength units squared [FSU]2. The fourth range of the HI-3001 is an auxiliary range not used by the two standard electric field probes. One additional probe can be used with the HI-3001 and used on the auxiliary (AUX) ranges. The two most sensitive range of the auxiliary probe can be used with the HI-3001. An attenuator is provided with the additional probe to provide the second range. To use the first (most sensitive) range of the additional probe, connect it directly to the meter in the normal manner. To use the second range of the additional probe, connect the probe to the attenuator and the attenuator to the probe handle. This effectively reduces the sensitivity of the additional probe by a factor of 10. Do NOT use the attenuator with either the GRE or the STE probes.
It should be noted that the HI-3000 series broadband meters were designed specifically to measure electric and magnetic fields associated with industrial and communication uses as opposed to the low duty cycle, short pulse modulation of microwave radar systems."
