1. INTRODUCTION

DESCRIPTION

The HI-4453/FP5083/FP4083/FP2083 Electric Field Probes
embody the latest innovations in isotropic sensor design and low
noise, miniaturized electronics. The HI­4453/FP5083/FP4083/FP2083 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 probe ideally suited for a wide
range of field monitoring applications. The HI­4453/FP5083/FP4083/FP2083 probes are excellent tools for
electric field mapping, RADHAZ measurements and EMC field
monitoring.

The basic HI-4453/FP5083/FP4083/FP2083 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-4453/FP5083/FP4083/FP2083 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-4453/FP5083/FP4083/FP2083 measures the field
strength in each of three axes. Frequency response of the HI­4453/FP5083/FP4083/FP2083 is 80 MHz to 40 GHz; dynamic
range is 3 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 and battery charger from their
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-4453/FP5083/FP4083/FP2083
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.

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.

Figure 2: Switch and Connectors

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 HI­4453/FP5083/FP4083/FP2083. 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-4453/FP5083/FP4083/FP2083 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-4453/FP5083/FP4083/FP2083
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-4453/FP5083/FP4083/FP2083
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-4453/FP5083/FP4083/FP2083 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-4453/FP5083/FP4083/FP2083 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.
The result is transmitted to the readout over glass fiber optic
cables. See "Probe Operation" for a more detailed explanation
of the functioning of the HI-4453/FP5083/FP4083/FP2083.

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 a computer with an RS232
serial port to communicated directly with the HI­4453/FP5083/FP4083/FP2083 via ETS-Lindgren’s optional HI­4413P Fiber Optic/RS232 Interface.

PROBE OPERATION

Receiver commands to the probe consist of the following:

• Send reading

• Read battery voltage

• Zero

• Set sleep timer

• Switch range

• Read temperature

• Enable axis

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 fed to the
instrumentation amplifier, whose output feeds the selectable
range/offset stage.

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.
