This chapter contains technical data, requirements and performance 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 rechargeable 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

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 consisting 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.

Contrary to all other Swan online process monitors the AMI INSPECTOR 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 destroy 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

The USP Operating Mode implemented in the firmware of the AMI
INSPECTOR Resistivity transmitter allows the measurement of
pharmaceutical water according to the USP <645>.
If the USP Operating Mode is set to <off> conductivity or resistivity
standard measurement is performed.
If the USP Operating Mode is set to <on>, the uncompensated
measuring values are compared with the values of an implemented
table defined by USP. If the deviation is too high, the Error 15 (USP
Error) is issued.

Alarm relay
Relay 1and 2
Signal output 3 (signal outputs 1 and 2 are deactivated)
Select a relay or signal output with the [ ] or [ ] keys,
press the [Enter]> key to confirm. Then change the value with the
[ ] or [ ] keys. After confirming the setting with the [Enter]
key, the value is simulated by the relay/signal output.
At the absence of any key activities, the instrument will switch back
to normal mode after 20 min. If you quit the menu, all simulated values will be reset.
3.2 Set Time
Adjust date and time.
3.3 Transmitter check
The AMI INSPECTOR Resistivity is delivered with a Swansensor
RC U with integrated cable. Therefore the Transmitter check is not
applicable with the AMI INSPECTOR Resistivity.
3.5 Fine adjust
The function “Fine Adjust” is only available if the AMI INSPECTOR
Resistivity is set to the measuring mode resistivity.
The function “Fine Adjust” is used to compensate a possible drift of
the electronic components. It is performed automatically every
night at 00:30 h.
It is also possible to start the function “Fine Adjust” manually in the
menu <Maintenance>/<Fine adjust>.

4.3 Logger
The instrument is equipped with an internal logger. The data can be
copied to a PC with the installed USB stick.
The Records consists of: Date, time, alarms, measuring value, raw
value (M), case temperature, flow.
4.3.1 Log Interval: Select a convenient log interval. Consult the table be-
low to estimate the max logging time. When the logging buffer is
full, the oldest data record is erased to make room for the newest
one (circular buffer).
Range: 1 Second to 1 hour
4.3.2 Clear Logger: If confirmed with yes, the complete logger data is de-
leted. A new data series is started.

As control
output
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
P-controller: The controller action is proportional to the devia-
tion from the setpoint. The controller is characterized by the
P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
PID-controller: The combination of a P-, an I - and a D-con-
troller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
Ziegler-Nichols method for the optimization of a PID controller:
Parameters: Setpoint, P-Band, Reset time, Derivative time
The point of intersection of the tangent with the respective axis will
result in the parameters a and L.
Consult the manual of the control unit for connecting and programming details. Choose control upwards or downwards.
