1. Area Monitor Probes
1.1. General Description
The Area Monitor Probe (AMP), a GM-tube based rate meter, is a state-of-the-art
microprocessor-based instrument. The AMP is designed for highly stable and accurate
measurements of dose rate from gamma radiation.
The AMP instrument is available in three versions:
AMP-50 - Covers a measuring range of 0.5 Sv/h up to 40,000 Sv/h.
AMP-100 - Covers a measuring range of 0.05 mSv/h up to 10,000 mSv/h.
AMP-200 - Covers a measuring range of 0.01 Sv/h up to 150 Sv/h.
AMP-300 - Covers a measuring range of 1 mSv/h up to 300 Sv/h.
The AMP is a lightweight and compact instrument with a large, four 7-segment LCD
display. The sophisticated software offers special features and optimal performance. The
wide dynamic range is obtained by automatic dead time correction, according to the preset
calibration. A special averaging function smoothes the readout and maintains fast response
time, while keeping the standard deviation at a minimum.
An automatic self-diagnostic procedure continuously checks both meter and detector and
reports any case of detector failure. The meter also alarms if the reading exceeds the
threshold value, or if the probe is in a field higher than the measuring range, or if the
battery potential drops below an acceptable value. The threshold can be selected from a list
of 11 preset values. When the meter is turned off the last parameters (threshold value,
calibration factor, dose status, communication mode, communication baud rate) are
retained in memory and will be recalled the next time the instrument is turned on.
The AMP may be used in one of four ways:
- by locally reading the smoothed digital display via the hand held meter display,
- by connecting the meter to a PC,
- by connecting the meter to an AM-16 Area Monitor (wired),
- by connecting the meter to an external WRM transmitter (wireless).
The AMP system contains four components (see Figure 1-1, AMP system block diagram):
meter, cable, probe head and communication interface. Connection between the meter and
the detector is accomplished via a four-wire shielded cable of up to 100 meters length. An
optional WRM transmitter may be connected via a standard four-wire telephone cable.
Two types of meter-to-PC cables are available.
The meter includes two boards: HV board and CPU board, including rate-meter and
display. A built-in RS-232 connection is used with the area monitor or WRM.
The detector includes an energy compensated GM tube, an amplifier and driver.
The AMP’s connections and probe head feature watertight sealing to allow for use in
underwater applications. Quick disconnect detectors allow customization of cable length
and facilitate easy de-contamination.

Area Monitor Probes / Operating & Maintenance Manual (Sv/h) Page 6
The detectors for the AMP-50, AMP-100 and AMP-200 include an energy compensated GM
tube, an amplifier and driver. The detector for the AMP-300 contains a silicon diode
The AMP’s connections and probe head feature watertight sealing to allow for use in
underwater applications. Quick disconnect detectors allow customization of cable length and
facilitate easy de-contamination.
1.2. Applications
 Real time monitor applications include any area with radiation levels from 0.01 Sv/h
up to 300 Sv/h. For example, the probe head may be placed directly onto a filter
housing or against a resin tank for the purpose of providing survey data or resin transfer
results.
 Replacement of traditionally “difficult to calibrate” underwater instruments.
 Provides a rugged detector for environments where the use of an electronic dosimeter is
undesirable.
 Provides real-time, remote monitoring in geometries developed for extendible “pole”
rate meters (TelePole, Teletector, etc.).
 Local readout of hand-held meter allows its use as a portable survey instrument.

verified by blinking of the “old” threshold value
3.7. Alarms
a. Detector alarm: If the detector is defective or
disconnected, the Err. LCDs will blink on the display and
an interrupted audible alarm will be activated. To mute the
audible alarm, press the SPEAKER push-button.
If the detector is defective the alarm will be activated as follows:
AMP-50 - after 2 minutes
AMP-100 - after 15 minutes
AMP-200 - after 120 minutes
AMP-300 - after 120 minutes
If the detector is disconnected for at least one second, the error and audio alarms are
activated. If the error condition (detector disconnection) lasts more than one minute, the
meter is turned off automatically.
b. Battery alarm: If battery voltage decreases below 6.2
Volts, the bAt. LCDs blink on the display and an
interrupted audible alarm is activated.
To display the measured readings and mute the audible
alarm, press the SPEAKER push-button. After the
SPEAKER push-button is pressed, the bAt. LCDs will reappear every five minutes for two
seconds, and every 30 minutes accompanied by an audible beep to remind users of the low

b. Overflow alarm: If the displayed count rate is higher than the
meter’s measuring range:
AMP-50 40,000 Sv/h,
AMP-100 10.000 mSv/h,
AMP-200 150 Sv/h,
AMP-300 300 Sv/h.

Area Monitor Probes / Operating & Maintenance Manual (Sv/h) Page 16
the OFLO LCDs blink on the display and an interrupted audible alarm is activated. To
mute the audible alarm, press the SPEAKER push-button.
d. Threshold alarm: If the reading exceeds threshold value,
the ALr. LCDs and the reading are displayed alternately,
accompanied by an audible beep.
Pressing the SPEAKER push-button mutes the audible alarm, but the ALr. LCDs and the
reading are continuing to be displayed alternately, until the reading decreases to 75% of the
threshold value. If the reading exceeds threshold value and then quickly decreases to below
75% of threshold value, the ALr. LCDs and the beep are automatically cancelled, even
though the SPEAKER push-button has not been pressed.

3.10. Battery Replacement
The battery compartment is located at the instrument back. To replace the battery, slide
out the battery compartment cover carefully. Use one 9-Volt alkaline battery; be sure to
connect it with the right polarity.
External Power Supply
The AMP is equipped with an external DC input, may be operated either with a 9V
battery or an external 9V DC power supply. The battery can be used in conjunction with
the external power supply. In case of external power failure the battery supplies the
current. The DC voltage should be 10 to 12 Volts, to avoid drain current from the battery.
The internal battery remains connected to function as a back-up power supply.
