1. INTRODUCTION

DESCRIPTION

The HI-4450/FP2080/FP4080/FP5080 Electric Field Probes embody the latest innovations in isotropic sensor design and low noise, miniaturized electronics. The HI4450/FP2080/FP4080/FP5080 probes are fully intelligent sensor enabling fast and accurate EMF measurements with industryleading performance specifications. Optical coupling to a variety of readout options makes this new probe ideally suited for a wide range of field monitoring applications. The HI4450/FP2080/FP4080/FP5080 probes are excellent tools for electric field mapping, RADHAZ measurements and EMC field monitoring.

The basic HI-4450/FP2080/FP4080/FP5080 probes are shipped complete with a 10 meter fiber extension cable, a carrying case, battery charger and connectors for extending the optic cable.

The HI-4450/FP2080/FP4080/FP5080 probe assembly consists of a spherical casing, containing the sensor, which is mounted on one end of a shaft; the other end of the shaft is attached to an extrusion that houses the electronics (Figure 1). The sensor and electronics housing operate-and are calibrated-as a unit.

The HI-4450/FP2080/FP4080/FP5080 measures the field strength in each of three axes. It performs a vector addition calculation on the readings and sends the resultant to the receiver via a fiber optic cable. Frequency response of the HI4450/FP2080/FP4080/FP5080 is 80 MHz to 40 GHz; dynamic range is 1 to 300 Volts per meter (V/m).

2. GETTING STARTED

UNPACKING AND ACCEPTANCE

Step 1. Upon delivery of your order, inspect the shipping container(s) for evidence of damage. Record any damage on the delivery receipt before signing. In case of concealed damage or loss, retain the packing materials for inspection by the carrier.

Step 2. Remove the probe from its shipping containers. Save the boxes and any protective packing materials for future use.

Step 3. Check all materials against the packing list to verify that the equipment received matches what was ordered. If you find any discrepancies, note them and call ETS-Lindgren Customer Service for further instructions.

Be sure that you are satisfied with the contents of your order and the condition of your equipment before installing the probe.

PROBE

A switch, two fiber optic connectors and a battery charger connector are mounted on the HI-4450/FP2080/FP4080/FP5080 electronics housing (Figure 2).

XMIT/RCV

The fiber optic cable assembly from the receiver is attached to the probe via two connectors. The cables are color-coded white for XMIT, yellow for RCV. Identically colored dots are located on the electronics housing adjacent to these connectors. Be sure that each cable is attached to the proper probe connector.

Figure 2: Switch and Connectors

When the fiber optic cables are not attached, always cover the probe connectors with the protective plastic covers supplied with the unit, or with similar material. This prevents dirt or other contaminants from entering the connector and causing communication problems.

ARM/OFF

The ARM/OFF switch activates and deactivates the probe. In the ARM position, its internal 3.6 VDC NiCd battery powers the probe: in the OFF position, the probe is inactive. To prolong battery life, set the ARM/OFF switch to OFF at the end of a test sequence or when the probe is not in use.

CHARGER

A standard fast charger is supplied with the HI4450/FP2080/FP4080/FP5080. When charging is complete, the fast charger acts as a trickle charger. The battery can be left on this maintenance mode indefinitely and its performance will not degrade.

BATTERY

The NiCd battery provides up to 17 hours of probe operation when fully charged.

BATTERY CHARGING

Each HI-4450/FP2080/FP4080/FP5080 probe contains a rechargeable nickel-cadmium (NiCd) battery. A fully-charged battery (nominal output voltage of 3.6 VDC) provides up to 17 hours of continuous operation.

NOTE: ETS-Lindgren charges the internal NiCd battery of the HI-4450/FP2080/FP4080/FP5080 at the factory in order to calibrate the probe prior to shipment. While every effort is made to ensure that your probe arrives ready to use, we cannot guarantee that this will be the case. Always check the condition of the probe's battery prior to making any measurements.

CHARGING PROCEDURE

Step 1. Plug the charger into a suitable AC source. Step 2. Set the probe switch to OFF. Insert the plug on the

charger cable into the probe's CHARGER jack. Step 3. The battery is now charging. This may take

approximately one hour, depending on how deeply the batteries are discharged. When charging is complete, the charger automatically goes into a trickle charge and will continue to do so until the probe is disconnected.

BATTERY TIPS

NiCd batteries have several characteristics that can affect both their performance and operating life. The following tips advise you how to take advantage of these characteristics to get the most out of your probe’s battery.

• Although NiCd batteries are rated for operation in temperatures from -20°C to +65°C (-4 °F to +140 °F), operating the probe in extreme temperatures will reduce operating time significantly. The optimum operating temperature range for these batteries is +20°C to +30°C (+68°F to +86°F).

• The battery in the HI-4450/FP2080/FP4080/FP5080 probe 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, be sure that the battery is fully charged before resuming field operation.

• If the battery exhibits low terminal voltage during charging, or if it appears unable to acquire or maintain an appreciable charge, individual cells in the battery may be shorted or damaged. If, for any reason, your battery needs replacement, contact ETS-Lindgren Customer Service for assistance.

3. OPERATION

This section discusses the theory of operation and the functions of the HI-4450/FP2080/FP4080/FP5080 Isotropic Electric Field Probe. A high-level block diagram (Figure 3) is included to aid the discussion. The objective is to provide information enhancing user understanding of the design of this probe.

SYSTEM THEORY

The HI-4450/FP2080/FP4080/FP5080 Broadband Isotropic Electric Field Probe utilizes a microprocessor for intelligent operation and control. The probe's self-contained power supply employs a 3.6 VDC NiCd battery, which provides up to 17 hours of continuous operation.

For each axis, the probe measures the radio frequency signal level and generates a linearized reading of the measurement. A vector addition is performed on these three readings: the result is transmitted to the readout over glass fiber optic cables. See "Probe Operation" below for a more detailed explanation of the functioning of the HI-4450/FP2080/FP4080/FP5080.

The probe relays data to the readout via either a short form or long form output word. See Appendix B for details on both output word formats.

For some applications, you may use any computer with an RS232 serial port to communicated directly with the HI4450/FP2080/FP4080/FP5080 via ETS-Lindgren’s optional HI4413P Fiber Optic/RS232 Interface.

PROBE OPERATION

Receiver commands to the probe consist of the following:

• Sending reading

• Switch range

• Read battery voltage

• Zero

• Read temperature

• Enable axis

• Set sleep timer

The signal flow within the probe is shown in the block diagram. To measure field strength, three mutually orthogonal dipole

antennas (one per axis) are used to provide an isotropic response to the ambient field. The signal from each axis is fed to a Schottky diode detector operating in its Square-Law region. After filtering, the signals generated by each axis are added vectorially: the result is fed to the instrumentation amplifier, whose output feeds the selectable range/offset stage.

NOTE: The HI-4450/FP2080/FP4080/FP5080 does not allow the option of measuring on an individual axis: all three axes are active at all times. Consequently, the change axis commands have no effect.

For each of the four ranges, the selectable range and offset stage provides a coarse analog zero for the measured signal. The output of the range/offset stage is fed to the A/D multiplexer, then to the analog-to-digital (A/D) converter itself.

After acquiring the composite three-axis signal, the microprocessor commands the A/D multiplexer to read the battery voltage and temperature sensing lines.

Data from the A/D converter is fed to the microprocessor, which transmits it to the receiver.

The EEPROM stores all calibration data for the probe.
