Page 17: Hi-3638 Controls And Connectors
ETS-Lindgren Product Information Bulletin included with your shipment. Following is a description of the controls and connectors for the HI-3638 ELF/VLF Electric Field Meter. Transmit / Receive Plug the fiber optic cable from the HI-4416 Digital Readout/Control Unit into the TRANSMIT connector and RECEIVE connector on the HI-3638, matching white to white (for transmit) and yellow to yellow (for receive). -
Page 18: Elf/Off/Vlf
This switch activates and deactivates the HI-3638 as well as the selection of ELF or VLF bands. LEDs indicate which band is selected. In the ELF or VLF position the HI-3638 is powered by the internal 12 VDC nickel-cadminum (NiCd) battery. To prolong battery life, set the switch to OFF when not in use. -
Page 19: Battery Charger
Disconnect the battery charger from power. Use a small screwdriver to loosen and remove the fuse assembly from the power entry module. Slide the small board located on the back of the fuse assembly from right to left to remove it. www.ets-lindgren.com Battery Charger... -
Page 20: Charging The Battery
Connect the battery charger to a power source. Switch the HI-3638 to OFF. Insert the charging plug into the CHARGE connector on the HI-3638. When the charging plug is connected, the LED on the battery charger illuminates. It remains illuminated until the charging plug is disconnected. -
Page 21: Battery Tips
C (+68 F to +86 HARGING The HI-3638 battery does not require periodic deep discharges to reverse the capacity-depleting memory effect caused by repeated shallow discharges; however, undercharging can reduce battery capacity. Therefore, after the charging procedure is complete, verify that the battery is fully charged before resuming field operation. - Page 22 This page intentionally left blank.

Page 23: Application
6.0 Application Meter The HI-3638 ELF/VLF Electric Field Meter is a single axis meter (responsive to one polarization component at a time) designed to be responsive to electric fields, including non-sinusoidal waveforms, from 5 Hz to 400 kHz. When the HI-3638 is immersed in an electric field, the sensor generates a current. - Page 24 The HI-3638 uses this principle to detect electric fields by measuring the displacement current caused by the ambient field between two closely spaced circular disks. By placing such a detector in a known electric field, the displacement current can be related directly to the magnitude of the field causing it, permitting calibration.

Page 25: Power Frequency Fields
7.0 Power Frequency Fields Before connecting or operating any component, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment. Use care when operating this instrument near energized conductors. www.ets-lindgren.com Power Frequency Fields... - Page 26 At other points the fields from the conductors may destructively add leading to minima in the fields. Thus, power line fields can have rather complex spatial distributions about the line. Power Frequency Fields www.ets-lindgren.com...
- Page 27 This same phenomenon occurs with virtually any grounded object immersed in the electric field environment of a power line and can be confirmed through field measurements. www.ets-lindgren.com Power Frequency Fields...
- Page 28 In addition, the presence of the operator will tend to perturb the electric field that is being measured. The operator should remain approximately one to two times their height away from the HI-3638 sensor. Power Frequency Fields...
