2. Product Description
This chapter contains technical data, requirements and perfor-
mance data.
2.1. Description of the System
The portable AMI INSPECTOR instrument is a complete monitoring
system mounted on a small panel with supporting stand and a re-
chargeable battery for stand-alone operation (>24h), designed as
an inspection equipment for quality assurance of online process
monitors.
Features General Features of AMI INSPECTORs are:
Battery life after full charge:
– >24h at full load (use of 3 relays, USB, signal output, logger)
– >36h at minimum load (use of logger only)
Charging time: approx. 6 hours
Controlled shut-down if battery is empty.
Display of remaining battery life in hours.
For longer battery life the back light of the LC Display is dis-
abled.
Continuous operation using power adapter. The battery
should be discharged at least once a month (normal usage
until the monitor automatically shuts down).
Battery The Li-Ion battery is located in the housing of the AMI transmitter.
See chapter Power Supply, p. 16 regarding power supply and
charging of the battery.
Sensor Swansensor RC-U high precision two-wire electrode made of stain-
less steel with integrated NTC temperature probe.
Application
Range
The resistivity is a parameter for the total quantity of ions present in
the solution. It can be used for the controlling of:
the condition of waters
water purification
water hardness
completeness of ion analysis

AMI INSPECTOR Resistivity
Product Description
Safety features No data loss after power failure, all data is saved in non-volatile
memory. Over voltage protection of in- and outputs.
Galvanic separation of measuring inputs and signal outputs.
USB interface Built-in USB interface for logger download. Use the USB stick sup-
plied by Swan only (other USB sticks can dramatically reduce bat-
tery life).
Signal
Output
One signal output programmable for measured values (freely
scaleable, linear or bilinear) or as continuous control output (control
parameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 Ω
Relay Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with au-
tomatic hold function.
Maximum load: 100 mA/50 VAC
Alarm Relay One potential free contact.
Alternatively:
Open during normal operation, closed on error and loss of
power.
Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values and in-
strument faults.
Input For potential-free contact to freeze the measuring value or to inter-
rupt control in automated installations (hold function or remote-off)
Measuring
Principle
The resistivity of high purity water is determined with a sensor con-
sisting of two metal electrodes. The characteristics of each sensor
is expressed as cell constant. An alternating voltage (to minimize
polarization effects) is applied to two electrodes. Depending on the
concentration of ions in the sample, a signal results between the
electrodes which is proportional to the resistivity of the water.
The measuring result is indicated as resistivity.

Product Description
Fluidics The flow cell (QV-Hflow) consists of the flow cell block [D], the flow
sensor [B] and the flow regulating valve [E].
The conductivity sensor RC-U [A] with integrated temperature sen-
sor is screwed into the flow cell block [D].
The sample enters at the sample inlet [F]. It flows through the flow
regulating valve [E], where the flow rate can be adjusted. Then the
sample flows through the flow cell block [D] were the conductivity of
the sample is measured.
The sample leaves the flow cell block via flow meter through the
sample outlet [C].

free from blemishes for approximately 1,5 x tube diameter from the
end.
Lubrication with lubricating oil, MoS2, Teflon etc. is recommended
for the assembly and reassembly of bigger sized unions (thread,
compression cone).
Installation 1 Insert the compression ferrule [C] and the compression
cone [D] into the union nut [B].
2Screw on the union nut onto the body, do not tighten it.
3Push the stainless steel pipe through the union nut as far as it
reaches the stop of the body
4Tighten down the union nut 1¾ rotation using an open ended

CAUTION
Use only the terminals shown in this diagram, and only for the
mentioned purpose. Use of any other terminals will cause short
circuits with possible corresponding consequences to material
and personnel.

3.3.2 Power Supply
Contrary to all other Swan online process monitors the AMI IN-
SPECTOR transmitter is supplied with power by battery only. The
rechargeable battery (Li-Ion) enables a stand-alone operation for at
least 24 hours.
WARNING
Do not provide power directly to the transmitter as this will de-
stroy the motherboard. All AMI INSPECTOR transmitters are
supplied with power by battery only.
Charging Use the original supplied power adapter to charge AMI INSPEC-
TOR only. Charging time: approx 6h.
Fully charged a stand-alone operating time of at least 24h is guar-
anteed:
>24h at full load (use of 3 relays, USB, signal outputs, logger)
>36h at minimal load (use of logger only)
In case that the battery is discharged completely the firmware will
automatically shut down.
Switch Power
ON - OFF
Switch the instrument ON or OFF using the toggle switch on the
transmitter.
Continuous
operation
For continuous operation use the power adapter as well.
CAUTION
If the AMI powers ON and then immediately shuts OFF, the
battery is empty. Do not hold the toggle switch in ON position,
as this can damage the battery.
CAUTION
During charging protect from heat impact and keep splash-
proof (plug of power adapter is not IP66).
Do not supply external devices, e.g. pumps, magnetic valves
or any other current consumers with AMI INSPECTOR
CAUTION
Use the original supplied power adapter to charge AMI IN-
SPECTOR only. Use of any other power adapter can damage
the battery or cause malfunction
