1 Description

The Flow Meter FC01-LQ is designed to detect flow speed, flow volume and medium temperature
of water (other liquids upon request).

These quantities are made available to the user as analogue electrical signals, physically isolated,
as current or voltage output and may be monitored by means of a limit monitor.

As relay outputs or transistor outputs the digital signals enable the user to integrate the FC01-LQ
into a control and monitoring system.

The transistor outputs enable the user to additionally process fault, status and volume pulse
indications in the control system.

The Flow Meter FC01-LQ may be used with calorimetric monitoring heads type CSx

(CSP, CSF).

1.1 Calorimetric monitoring procedure

The calorimetric measuring procedure is based on the physics of heat dissipation.
A body with a temperature higher than its surroundings supplies a medium flowing past that

body with energy in the form of heat. The amount energy supplied is a function of temperature
difference ∆ϑ and mass flow.

The thermal measuring method CTD (Constant-Temperature-Difference) is based on following
principle:

The temperature difference ∆ϑ between the two sensors is kept constant and the mass flow is
determined by measuring the calorific power.

Fig. 1 is a schematic diagram of a CTD method based sensor.
Two temperature-sensitive resistors (sensor elements RS and RM) are immersed in the medium.

Sensor RM assumes the temperature of the medium ϑ

M

whilst heater resistor RH heats element

RS to temperature ϑ

S

. As a function of the medium, the temperature differential ∆ϑ = ϑS- ϑMis
preselected as a reference variable by the CTD control and is kept constant. The r equir ed heater
current I

H

is a function of mass flow so that the control variable y of the control can be used for

evaluation.
Major benefits of this method are:

● Fast response, particularly to sudden flow standstill.

● Medium temperature measurement, providing optimum temperature compensation.

● Increased safety because the sensor cannot be overheated during flow standstill.

The flow rate is determined by mass flow.

The power supply is physically isolated between power supply input and system power
supply output. This also applies to the analogue and signal outputs which are physically
isolated from each other as well as from the other electronics.

There is no electrical isolation between monitoring head and central electronic unit.
Connection of the monitoring heads is by means of precut cable links.
Cables and user interface connections are shown in para. 2.3.2 and circuit diagram 2.3.2.1/ 2.3.2.2.
System configuration and parameter setting are by means of the keyboard if default values

need to be changed. (paras. 5 and 6)
This mainly applies to monitoring head selection, signal outputs (switch point setting) and

analogue outputs (zero point setting and scaling).

1.2.1 User interfaces

Signal outputs: 1. R2 - Relays outputs (2 limit values)

(optional) Two-channel physical isolation, relay change over contact

The channels may be assigned in menu “CONFIGURATION”, either
individually or in pairs, to the physical quantities of temperature or
flow. The switch on and off values can be set as desired in menu
“PARAMETERS” (yet within the measuring range) for each contact.

Please see para. 8.4.1 for electrical connection.

2. T4 - Transistor outputs (2 setpoints + 2 status outputs or 2 setpoints +
1 status output + frequency output)

Four-channel physical isolation, transistor output - collector/emitter
(NPN) freely connectable

Channel 1: common error signal
Channel 2: busy signal or frequency output
Channels 3 and 4: Both channels may be assigned individually or in

pairs to the physical quantities of temperature or flow. The switch on
or off values of each transistor output can be set as desired.

Please see para. 8.4.2 for electrical connection.

Analogue outputs: Two-channel physical isolation, current or voltage output
(optional) Please see the ordering number to find out whether it is a current or

voltage output.
Output quantities: 0/1 - 5 V FS (option V1)

0/2 - 10 V FS (option V2)
0/4 - 20 mA FS (option C1)

These FS (full scale) output quantities apply to both channels (flow and
temperature) as standard.

20% zero elevation and FS value can be programmed. (See para. 5.11)
Shield connections are ungrounded.

The shields of the signal cables should be applied on one side only.

Power supply: DC 24 V supply

Internal switch mode power supply with physical isolation of the
primary and secondary side.

Noise emission on the connection cable is limited by circuit design
and filter.

A PTC resistor provides protection from overcurrent. The element
automatically resets upon removal of the disturbance or after
disconnection of the supply voltage of the FC01-LQ for approx. 1 s
(e.g. remove terminal XV).

Please see para. 8.2.1 for technical characteristics.

2 Installation

These are general directions for the application of calorimetric measuring heads which from
application to application should be reviewed by the user in accordance with individual
requirements.

2.1 Selection of material

Stainless steel 1.4571 / AISI 316 Ti

The standard monitoring head material is stainless steel 1.4571/AISI 316 Ti, an austenitic, acid­resisting stainless steel that is commonly used throughout industry. Manufacturers claim it also
withstands oxidizing organic and anorganic acids, and partly even reductive media.

The resistance of this stainless steel should however be verified by the user, particularly when it
is used in medium mixtures that may from time to time be exchanged with cleansing agents. Its
chemical resistance also depends on temperature, flow rate and concentration of the medium.

Stainless steels owe their resistance to rust mainly to their alloy combination with chromium, the
formation of chromic oxide on the steel surface resulting in a passive state. Contamination,
deposits on the surface, or foreign rust may however neutralize the passivity. Therefore care
should be taken to keep the surfaces clean.

Stainless steel heads must not get in contact with steel parts other than stainless steel or with
chemically dissimilar metals, as this would cause electrolytic corrosion.

Nickel-based alloy (Hastelloy 2.4610)

Hastelloy 2.6410 is a material with a chemical resistance generally exceeding that of stainless
steel and copper-based alloys. They are particularly suitable for alkaline media (pH > 7). They
should however be examined for suitability for each specific application using resistance tables
and pragmatical values.

2.2.1.2 Mounting instructions (monitoring head CSP-.. with sensor adapter TP-.. )

Caution!

The monitoring head should only be installed or removed when the pipes are unpressurised.

To ensure the safety label is clearly visible, it should be affixed on to or close to the measuring point.

● Insert the monitoring head with the O ring into the sensor adapter and tighten the union
nut (observe correct retention).

The retention pin ensures correct alignment of the monitoring head after the union nut has
been tightened.

Correct immersion depth of the monitoring head is ensured by the stop provided.
Sealing of the monitoring head in the sensor adapter is by means of the O ring provided (fig. 3).

● Screw the sensor adapter into the pipe, using hemp or teflon tape for sealing.

2.2.2.1 Mounting instructions for monitoring head CSF-11

Caution!

The two sensors (M) should be screwed into the pipeline far enough to ensure that they
are aligned side by side directly across the direction of flow. The sensors are correctly
positioned when the wrench flats (S) are aligned parallel with the pipeline.

The shoulder of the sensor (7 mm from the tip) must be at the position 1/8 from dia. i.

● In the case of vertical pipelines the monitoring head should be installed where the flow is
rising, if possible.

● For horizontal pipelines the monitoring head should be mounted on the underside of the
line (suspended).

2.3.2.3 Electrical connection - frequency output (version FC01-LQ-U1T4)

The quantity-dependent pulse may be selected in the menu item “DISPLAY SELECT”. A square
pulse signal is available for driving a counter or a primary control at the plug XAH /BUSY E/- and
/BUSY C/+ (pins 3 and 4) (see fig. 16 - circuit diagram FC01-LQ - transistor outputs).

Signal ground shall be connected to pin 3 (BUSY E/-) and the driving load to pin 4 (BUSY C/+).
The pulse length is 50 ms (±1%) continuously.
Select cable size ≤1.5 mm

2

to make the connections.

The shield cables can be connected to connector XAS, pin 3.
Electronic signal processing (fig. 17)

If the frequency output of the FC01-LQ is connected to an electronic counter, computer or PLC,
the load current should not exceed 10 mA so as to ensure low level is 0.8 V. The max. admissible
voltage level of 48 V is irrelevant in this connection.

Typical circuit (example 1)

Electromechanical pulse counter (fig. 18)
The FC01-LQ driver output comprises an integral safety circuit which when isolating the counter

operating coil will limit overvoltages caused by inductance and convert the energy stored.
The counter should be able of processing a counting frequency of ≥10 Hz, as the puls e length

is 50 ms (±0.1%) constinuously.
It should therefore be ensured that the counter can be increased by one during the time available.
If a separate relief network is preferred to the integral network, care should be taken when

processing the max. frequency of 10 Hz to ensure the energy stored in the operating coil has
dissipated by the time the counter output is reset. The time to do this should be below 40 ms,
making due consideration to switching times and pulse variations.

Typical circuit (example 2)

Note:

❑ As there will be a reset pulse available at the output in the moment the supply voltage of

the FC01-LQ is applied, make sure that the counter is switched on delayed or set to zero
after it has been switched on

3 Operating system

Clear menu-driven control, via keyboard and display, enables easy definition of parameters and
configuration. This provides high system flexibility, making the FC01-LQ the optimum solution
for a wide variety of measuring, monitoring and display tasks.

All functions are distributed on the three following menu levels:

See Appendix 2 listing all functions available.

Keypads MODE, UP and DOWN

Setting and configuration is by means of three front keypads MODE, UP and DOWN.
It is also required for setting the unit to simultaneously press UP and DOWN =

.

Caution!

The FC01-LQ can only be set or operated when connector XTF (keyboard release) is
removed!

Menu paging

The next menu option is selected by pressing MODE (forward paging)

.

Pressing MODE after the last menu option will cause skipping to the first option of the menu.

Calling a menu option

Simultaneously pressing UP and DOWN = calls the selected menu option, or
causes skipping to the selected submenu.

Entry of numerals

Some menu options require numerical values to be entered. After selecting the appropriate
menu option, the value indicated can be changed by pressing UP or DOWN.

Each time UP or DOWN are pressed, the value indicated will be increased and reduced
respectively, by one numeral skip.

The longer UP or DOWN are pressed, the faster the increase or reduction.

Transfer of entries

Pressing MODE transfers the set value or the selected menu option to a volatile memory.
A permanent transfer of settings and values is only effected when quitting the menu, after a

plausibility check of all entries.
Afterwards the data are still available even after switching the FC01-LQ repeatedly on and off.

Deleting data

Selected data such as MIN, MAX values, totalized quantity or LAST ERROR can be deleted or
reset by simultaneously pressing UP and DOWN = .

Caution!

After configuration and parameter selection re-connect plug XTF (keyboard release) to
protect the system against unauthorised access!

4 Operation and main menu

4.1 Switch-on performance

Upon power application POWER ON TEST will be shown on the display for approx. 1 sec., with
the software version number being indicated in the second line.

During this period, the integral controller will conduct test routines (see para. 7.1, Test and diagnosis).
If during the test no error was found, the display will indicate HEATING UP. The FC01-LQ will

then be in the heating up period required for the measuring procedure.

4.2 Measuring cycle

Upon completion of the heating up period and availability of the first measured value, the display
will change to measuring cycle, and the user interfaces such as analogue outputs or limit
switches will be up-dated.

Note:

❒ It is not possible to configure or select parameters of the system during the measuring

operations!

All options of the main menu may be addressed without affecting the measuring and monitoring
function.

Menu option values

may be deleted simultaneously operating the UP and DOWN = switches without
affecting the measuring operations.

Over limits of the measuring range

Theoretically established measuring values will be used when the measuring range of
calorimetric monitoring heads is exceeded (0.05 … 3 m/s for water). The FM-LQ 1 can thus be
operated beyond the measuring values defined (up to 4 m/s for water).

This feature will not affect the accuracy specified for the measuring ranges defined whilst no
accuracy information can be given for conditions where the measuring ranges are exceeded.

Analogue output, limit switches etc. can be set beyond the measuring range. When per cent display
is selected, the defined measuring range will correspond to 0 ... 100% (>100% when the defined
range is exceeded).

The following operating data may be retrieved in the main menu during the measuring cycle: (see
para. 4.2.1).

4.2.1 Operating data

4.2.1.1 Measured value(s)

Flow rate and medium temperature are indicated by the units selected in the upper line of the
LC display.

The lower line of the display will optionally show the switching condition of the limit switches and
an analogue bar with a 10-segment resolution, or the flow volume/time unit pertinent to the
indicated flow rate or the totalized flow volume (totalizer function).

The analogue bar has different meanings, depending on its configuration (see para. 5.7 - menu
option BARGRAPH).

The limit switches are identified according to their physical assignment, i.e. by F for flow rate and
T for medium temperature, at the first or last place of the second line on the display.

If F and T are shown reversed, the limit switch is in the switch-on condition.
Limit switches lying within the analogue bar range are also represented at the appropriate place

of the analogue bar (see para. 5.7).
The following figures show the display variants under menu option “Measured value(s)” (para. 5.6 -

menu option DISPLAY SELECT and 5.9 - menu option FREQUENCY OUTPUT).

4.2.1.2 Peak values (menu option: PEAK VALUE MIN / PEAK VALUE MAX)
The FC01-LQ comprises four specific measured-values memories.

They store the lowest and highest value of flow rate and medium temperature.

fig. 21

After switch-on or NOT-BUSY indication, the minimum and maximum values are deleted and will
be continuously updated (non-return pointer principle).

The peak values may be retrived in the main menu and are deleted by simultaneously pressing

UP and DOWN = .

Caution!

Power failure or disconnection of the power supply will delete the contents of the four
measured-values memories.

4.2.1.3 Last error (menu option: LAST ERROR)
The last main menu option to be called is the error memory.

This error memory comprises the number of the last error (see section 7). It may be very helpful
when commissioning the FC01-LQ.

Other than the peak value memories described above, the contents of this memory will be
retained even upon power failure.

The user may purposely delete the error memory in the condition selected by simultaneously
pressing UP and DOWN = .

• GRAD FAHRENHEIT [°F]

• KELVIN [K]
All other entries relating to the medium temperature (limit value, analogue output, etc.) refer to

the unit selected there. When the temperature unit is changed, all configuration and parameter
data relating to medium temperature will automatically be converted.

5.6 Display (menu option: DISPLAY SELECT)

The FC01-LQ enables the user to define the 2nd line of the display 2 in certain points.
When the first line of the LC display in the main menu indicates the flow rate in the unit selected

as well as the medium temperature in °C, °F or K, it is possible to select the second line from
the following menu options (see para. 5.14).

• BARGRAPH Totalizer:

• LITRE/SECOND [l/s] • LITRE [l]

• LITRE/MINUTE [l/min] • METRE

3[m3

]

• METRE

3

/ HOUR [m3/h] • GALLONS° [° = US-GALLONS]

• GALLONS°/MINUTE
Where totalizer function has been selected, the totalizer will start at zero counting in the unit

selected (litre, m

3

or gallons).

When the display changes from m

3

to litre or gallons, or from litre or gallons to m3, the value

already counted will be converted.
The content of the totalizer is deleted by simultaneously pressing UP and DOWN =

, or when the max. display value (99999999.9 l, m

3

or gallons) is reached.

In both cases the totalizer will restart from zero.

▲ + ▼

▲

▼

Caution!

The content of the totalizer is deleted in the event of power failure or disconnection of the
power supply!

Skipping to the submenu BARGRAPH or PIPE SIZE is effected depending on the selected menu
option.

5.7 Bar graph (menu option: BARGRAPH)

This menu option allows the user to set the bar graph as desired. The following settings should
be made:

• FLOW / TE MP = (bar graph assignment: flow rate/me dium temperature)

• ZERO = (initial value of the bar graph)

• FS = (final value of the bar graph)
Independent of its assignment, the bar graph has a constant resolution of 10 segments.
When entering the initial or final value, the user should observe reasonable resolution!
The bar graph also comprises the representation of the limit switch(es) as far as they can be

indicated in the bar range selected.
The representation of the limit switches in the bar graph depends on the switch-on value of the

limit switch.
For representation details see para. 4.2.1 (Operating data).

Example:

Limit switch assignment: LS1 F and LS2 T
Switch-on value LS2: 23 °C
Switch-off value LS2: 29 °C
Analogue bar graph assignment: medium temperature
Initial value - analogue bar graph: 20 °C
Final value - analogue bar graph: 30 °C
Instantaneuous temperature value: 25 °C
resulting in the analogue bar graph display shown below:

5.8 Pipe diameter (menu option: PIPE SIZE)

If flow volume/time unit display has been selected, it is necessary to indicate the pipe diameter
to calculate mass flow.

This is provided by selecting the pipe diameter in menu option PIPE SIZE comprising pipe
diameters from 10.0 … 999.9 mm.

5.9 Frequency output (menu option: FREQUENCY OUTPUT)

The totalizer function of the FC01-LQ has been expanded by the output of proportional quantity
pulses. The function can only be displayed by version FC01-LQ-U1T4 (transistor outputs).

The proportional quantity pulses have been determined as follow:

Example: 1 pulse / 10.0 [litre]

The frequency output will supply 1 pulse per 10 litres (totalized quantity).

When the quantity-proportional pulses are assigned, the frequency of the frequency output must
no exceed 10 Hz. The limits that can be displayed are determined by the flow velocity range and
the pipe diameter.

Potential setting range of the frequency output: 1 pulse per 0.1 … 999.9 [litre], [m

3

], [gallons]

Behaviour of the frequency output when the max. frequency is exceeded

The max. frequency being exceeded will not cause the measurement to stop but will rather
cause the error output to signal error 60 on the display. This error is included in priority group III.

If a combination of priority III errors occurs simultaneously, they are indicated or stored in the
error memory observing the following sequence:

Error No. 20, 30, 60, 40, 41.

Behaviour of the frequency output when the measurement is stopped

When the measurement is stopped (as caused by priority II error and calling the configuration or
parameter selection menus), the pulses for the quantity already counted will be available.
Thereafter the output of pulses will be stopped, with the frequency output becoming high­resistive until the measurement is restarted.

Behaviour of the frequency output when the content of the totalizer is deleted

The content of the totalizer may be deleted by simultaneously pressing UP and DOWN
= in the main menu.
As the frequency output refers to the content of the totalizer, although its operation is not

dependent on the content of the totalizer, a totalized quantity that is smaller than that set per
pulse will not be lost.

This means that only the content of the totalizer is deleted.

5.10 Analogue output - flow rate (menu option: ANA OUT FLOW)

This menu option allows adjustment of the flow rate analogue output specifically to the
requirement of the entire system.

Options are:

• OFFSET = 0%/20% FS (0/4 … 20 mA, 0/1 … 5 V, 0/2 … 10 V)

• ZERO = (initial value 0(20) % corresponds to a flow rate of _ [m/s] [%] [FPS])

• FS = (final value 100% corresponds to a flow rate of _ [m/s] [%] [FPS])
When entering the initial or final value, the user should observe a reasonable resolution!
With a flow volume/time unit selected in menu DISPLAY SELECT and when setting the initial and

end values, the pertinent flow volumes will also be indicated.

5.11 Analogue output - medium temperature

(menu option: ANA OUT TEMP.)

In conformance with the configuration “Flow rate analogue output” it is possible to adjust the
medium temperature analogue output to the requirements of the entire system.

Options are:

• OFFSET = 0%/20% FS (0/4 … 20 mA, 0/1 … 5 V, 0/2 … 10 V)

• ZERO = (initial value 0(20) % corresponds to a medium temperature of … [°C] [°F] [K])

• FS = (final value 100% corr e sponds to a med ium te mperat ure o f … [°C] [°F] [K])
When entering the initial or final value, the user should observe a reasonable resolution!

5.12 Quitting the configuration menu

Upon configuration of the analogue outputs, the menu may be quitted or re-set to the start
(SENSOR SELECT).

To quit the configuration menu, the controller will check the data entered for plausibility.
“CONFIG. OK!” is indicated when the data are found correct. The menu may than be quitted by

pressing MODE.
Errors found during the plausibility check are indicated in the following sequence of priority.

Priority of entry errors in the CONFIGURATION menu:

• ERR. A-OUT FLOW OUT OF RANGE

(flow analogue output outside measuring range)

• ERR. A-OUT FLOW ZERO ≥ FS

(initial value ≥ final value with flow analogue output)

• ERR. A-OUT TEMP. OUT OF RANGE

(temperature analogue output outside measuring range)

• ERR. A-OUT TEMP. ZERO ≥ FS

(initial value ≥ final value with temperature analogue output)

M

• ERR. BARGRAPH OUT OF RANGE
(bar value outside measuring range)

• ERR. BARGRAPH ZERO ≥ FS
(bar initial value ≥ bar final value)

The menu can only be quitted after correction of the error(s). To do this, return to the beginning
of the configuration menu by pressing UP or DOWN and select the menu option with

the incorrect entry for correction.

Caution!

If during the configuration data are affected which are accessible in the parameter
selection menu, (which may be the case for the options Sensor Selection, Medium
Selection and Limit Switch Assignment), the option “PARAMETERS” in the main menu will
be flashing.

In this event it is imperative to branch into parameter selection menu to set the data in
conformance with the desired application.

Example: Changing the limit switch assignment from LS1 → F / LS2 → T to

LS1 → F / LS2 → F

Effects on
parameter data: LS2 ON = 0.00

LS2 OFF = end of measuring range (depending on the medium selected)

Reason: Changing the physical assignment of limit switch 2 will adjust its switch-on and

switch-off values to the new assignment (flow rate).

An overview of the configuration menu and a summary of the measuring ranges and menus
available for the sensor type selected are shown on the following pages.

6 Parameter selection (menu option: PARAMETERS)

After configuration of the FC01-LQ in conformance with its application (configuration menu), it
is possible to set parameters (e.g. limit values).

During parameter setting, measuring operations are not possible (see Appendix 1).
The following parameters may be set in the Parameter selection menu:

6.1 Measuring time (menu option: MEAS. TIME)

The measuring time may be set between 1 and 30 sec., referring both to flow rate and medium
temperature.

The effect of the measuring time may be compared to that of a filter; it is used to determine the
average of the last measured values (measuring time 100 ms) after each measurement.

The set measuring time does not influence the measuring rate and display up-date.

6.2 Limit switch 1 - switch-on value (menu option: LS1 ON = ......)

Limit switch 1 - switch-off value (menu option: LS1 OFF = ......)

Depending on the configuration (see configuration menu) limit value 1 may be set either for flow
rate or medium temperature.
The limit value may be set over the entire measuring range and is always related to the display
value.

Limit switch up-date is by measuring rate, independent of the set measuring time.
The hysteresis is determined by entering different switch-on and switch-off values. Its magnitude

should be reasonably adjusted to current operating conditions.
A specific definition of the operation (closed-current or open-circuit principle) may be dropped

by separately entering the switch-on and switch-off value of the limit switch, because the
definition is deducted from the switch-on and switch-off value..

FC01-LQ with transistor outputs (option T4):

• LIM1E - LIM1C = switched

Example 2: Switch-on value higher than switch-off value

Example for ON: as described in example 1 (fig. 23)

With limit switch 1 set for flow rate and a flow volume/time unit selected in menu DISPLAY
SELECT, and when setting the switch-on and switch-off value, the pertinent flow volumes will
also be indicated.

6.3 Limit switch 2 - switch-on value (menu option: LS2 ON = ......)

Limit switch 2 - switch-off value (menu option: LS2 OFF = ......)

See limit switch 1!

6.4 Scaling factor (menu option: FLOWSCALE)

The scaling factor influences flow rate indication.
The factor, which may be set between 0.01 and 9.99, allows flow rate indication changes

(increasing or reducing the measured value in the display).
For example, the scaling factor may be used to indicate the average flow rate in the pipeline

rather than that available at the sensor.

6.5 Quitting the parameter selection menu

Before the parameter selection menu can be quitted, the controller will conduct a plausibility
check of the data entered.

“PARAMETERS OK!” is indicated when the data are found to be correct. The menu may then be
quitted by pressing MODE.

Errors found during the plausibility check are indicated in the following sequence of priority.
Priority of entry errors in the PARAMETER SELECTION menu:

• ERROR LS1 OUT OF RANGE
switch-on and/or switch-off value for limit switch 1 outside measuring range

• ERROR LS2 OUT OF RANGE
switch-on and/or switch-off value for limit switch 2 outside measuring range

• ERROR LS1 ON = OFF
switch-on value for limit switch 1 equals switch-off value for limit switch 1

• ERROR LS2 ON = OFF
switch-on value for limit switch 2 equals switch-off value for limit switch 2

The menu can only be quitted after correction of the error(s). To do this, return to the beginning
of the parameter selection menu by pressing UP or DOWN and select the menu option
with the incorrect entry for correction.

7 Errors

7.1 Test and diagnosis

The FC01-LQ is provided with extensive test and diagnosis functions which may be classified
as follows:

7.1.1 Priority group I

Priority group I comprises the switch-on test routines (FC01-LQ self-test) which are carried out
when the system is switched on.

Their implementation is indicated.
Errors No. 1 to 5 do not allow system operation.
The test routines may be repeated by pressing any of the switches.
If even after several trials the switch-on test cannot be conducted without error indication, the

system should be returned to the supplier for rectification, indicating the error number.
Priority I errors cannot be rectified by the user!

7.1.2 Priority group II

These test functions are continuously carried out during operation. The occurrence of errors
No. 10 and 21 will cause measurements to stop, indicating the error and monitoring the source
of the error. Upon rectification of the error, the system will automatically return to measuring
operation.

7.1.3 Priority group III

These test routines are also continuously carried out during operation.
Other than the above priority groups, errors No. 20, 30, 60, 40 and 41 will not cause

measurements to stop; the error output will indicate and the number of the error will be shown
on the display.

7.2 Potential errors

Independent of the priority group, all errors found are indicated with their relevant number.
In order to facilitate operation, the last error is stored in a non-volatile memory. The stored error

may be retrieved and deleted in the main menu.
If a combination of errors occurs simultaneously, they are indicated or stored in the error memory

observing the following sequence.

Priority group I
