Accessing to programmed parameters
Thanks to the tree structure, the programming routines allow to access to one parameter and modify it without passing
through the whole list of parameters.
To advance through programming
The progress through the programming routines is done by pressing
key.
In general, the steps to be done will be push
key a certain number of times to select an option and push key to
validate the change and going forward to the next step of the program.
The numerical values are programmed digit by digit as explained in the next paragraph.
Programming numerical values
When the parameter is a numerical value, the first of the digits to be programmed will appear blinking on display.
The method of introducing a value is as follow:
Digit selecting: Press repeatedly the key to shift from left to right over all the display digits included the LED
direction indicators (when the programmed function requires it).
Changing the digit value: Press repeatedly the
key to increase the value of blinking digit until it has the desired
value or to alternate the LED Up and Down arrows indicators (MAX and MIN).
Selecting an option from the list
When the parameter is an option to be chosen among different possibilities, the
key allows you to browse through
the list of options until you find the desired parameter

3.3 Counter configuration
INPUTS
The counter has two inputs, the A input receives the
pulses to count, and the B input serves to inhibit the
count or to change the count direction, except in case of
bidirectional counter IndEP where the second input is
also used to count pulses.
PULSE MEASUREMENT
The pulses applied to the input are detected in the rising
edge and immediately update the value of the counter
and the setpoints status if the card is installed. The
display updates every 100 ms. In a power failure or
disconnection from the supply source, the instrument
keeps the count values.
VARIABLES
The main variable of the counter is the PROCESS
variable that is the number of pulses registered from the
last RESET operation.
If the totalizer option is enabled, we have PROC and
TOTAL variables.
The TOTAL variable counts the total number of pulses
received, independently of the reset operations that may
take place in the process display.
DISPLAY
Process: The limits of the display are 99999 and -
99999. When the instrument exceeds 99999, it shows
OVER, and when it falls below -99999, it shows UNDER.
The positive sign is indicated by the red LED Up arrow
located on the left side of the display and the negative
sign is indicated by the red LED Down arrow located on
the left side of the display.
The decimal point can be located in anyone of the digits
of the display, and it has not value, that is, the display
always shows the whole part of the measurement.
Total: The limits of the display are 99999999 and
-9999999. When the instrument exceeds these limits the
display shows the indications OVER or UNDER.
The negative sign, when the value has less than five
digits, appears in the most significant digit of the
display.
The negative sign is indicated by the MIN LED.
When the total value has more than five digits, the
display alternates the 4 digits high order part and the 4
digits low order part (the letters 'H' and 'L' in the
auxiliary digit indicate which part is on display.
The decimal point can be located in anyone of the digits
of the low part, and it does not have value, the display
shows the whole part of the measurement.
3.3 Counter configuration
INPUTS
The counter has two inputs, the A input receives the
pulses to count, and the B input serves to inhibit the
count or to change the count direction, except in case of
bidirectional counter IndEP where the second input is
also used to count pulses.
PULSE MEASUREMENT
The pulses applied to the input are detected in the rising
DISPLAY
Process: The limits of the display are 99999 and -
99999. When the instrument exceeds 99999, it shows
OVER, and when it falls below -99999, it shows UNDER.
The positive sign is indicated by the red LED Up arrow
located on the left side of the display and the negative
sign is indicated by the red LED Down arrow located on
the left side of the display.
The decimal point can be located in anyone of the digits
of the display, and it has not value, that is, the display

3.4. Mode count programming
The input setup is available on the 'CnInp' module which
allows configuration of the count mode and batch operation.
3.1.1. Count Modes
The software provides setup for five different count modes:
uP
Up count
do
Down count.
In-A
Allows count on A input regardless of input B
InA-B
Pulses applied at the A input are added or subtracted to the
count display if the B input is at low level and being used as
inhibited input.
uP-do IndEP
Pulses applied at the A input are added to the count display
while pulses at the B input are subtracted.
uP-do dIrEC
When B input is at low level, the pulses applied at the A
input increment the count. When B input is at high level, the
pulses at the A input decrement the count.
uP-do PHASE
The rising edges at the A input increment the count if the B
iinput is at low level. The falling edges at the A input
decrement the count if the B input is at low level.
Unidirectional counters:

3.5. Scaling setup
3.5.1. Options of the Process Variable
In the menu ProC of the CndSP module can be found the
parameters related to the PROCESS variable measurement, Decimal Point, Offset, Multiplier Factor-
DECIMAL POINT
The decimal point indication helps to read the display in the
desired engineering units.
The decimal point has no real value, i.e. the digits to the right
of the decimal point are not actually decimals. To read values
with resolution to the desired decimal places is achieved by a
combination of decimal point and scaling factor.
For example, suppose a system that provides 100 pulses per 2
meters length of a material. To display length in meters and
centimeters, you should program a factor of 2 (1 pulse = 2
cms) and place the decimal point to the third digit.
OFFSET
OFFSET is the value that takes the counter in a reset event.
By default it is zero whatever is the configuration.
Configurable in the menu ProC
The OFFSET is applied to the PROCESS variable exclusively.
When the OFFSET is different from zero, the LED TARE will
remain active while in the run mode.
SCALE FACTOR
The scale factor is programmable from 0.00001 to 99999.
Individual decimal point location makes possible to
program any value within this range independently from
the main decimal point of the display.
Any number below 1 act like a divisor while a number
above 1 acts like a multiplier. (It is not possible to program
a factor=0).

When the total value is between -9999 and 99999, it is shown
on the display with the letter ‘L’ in the auxiliary digit and with
the red led up and down arrows for positive and negative.
(positive)
(negative)
When the accumulated value exceeds from four digits, the
display alternates a 4 digit high order part (with the letter 'H'
in the auxiliary digit) and a 4 digit low order part (indicated by
the letter 'L' in the auxiliary digit).
(The switching between high and low order parts takes place
at a rate of approximately 2s each part).
3.5.3. Totalizer Option
The totalizer facility can be enabled and disabled by
software.
The totalizer counter shares the same input setup, count
mode and count direction as the process counter but
provides separate decimal point and scaling factor.
Each pulse received at the input increment or decrement
the process and total counters exactly, although the
display value may vary from one to another according to
individual scaling factor and reset operations.
The limits of the display are -9999999 and 99999999
(7 digits with minus sign or 8 digits).
The decimal point can be set to five decimal places.
The scaling factor is programmable between 0.00001
and 99999 as for the process counter.
The totalizer has no possibility to load a user selected
display value in a reset event.
3.5.4. Totalizer visualisation

4. CHRONOMETER CONFIGURATION
INPUTS
The meter has two inputs for the START and STOP
signals that provide different types of time measurement
according to input setup (see page 23 "Start and Stop
Modes").
There are three selectable operating modes:
mode In-A, that allows to measure the width of a pulse,
and mode In-AB, that is used to measure the difference
between two signals
t
t
MEASURE
Time measurement is initiated on a rising edge of the
START input. This starts up an internal counter which is
controlled by a high precision crystal quartz clock.
The STOP signal suspends the internal count keeping the
value of the counter to the START of following time
measurement cycle.
The counter is missed to zero in a RESET operation.
In a disconnection from the power source, the instrument
saves the count value reached internally.
DISPLAY
The display can not be scaled, it only reads time in the units
selected according to the programmed time range.
The decimal point appears at a fixed position according to
time range.
OFFSET
An offset value can be programmed for example to count
down to zero from the preset time value.
The measured value, and the alarms if they exist, is
updated in each minimum unit of the selected magnitude.
Display refreshment: each 100ms.

5. FREQUENCY METER / TACHOMETER CONFIGURATION
INPUTS
In frequency/tachometer mode both inputs of the meter
are used. The signal providing frequency/rate and count
information must be issued to the A input. A second
signal may be applied to the B input to control direction
of rotation or polarity of the signal.
MEASURE
The method of calculating rate is based in measuring
the period of the signal, that is, the time elapsed
between two consecutive rising edges. The period is
converted into a high precision frequency value and
scaled to read desired units.
DISPLAY
The meter allows the user to change some parameters
to fit the particular application needs, such as to reduce
or extend the number of signal cycles of each reading,
the time limit, the display rate and averaging (see
"Options of the Process Variable" in pages 29 and 30).
TOTALIZER
If enabled, the totalizer accumulates the number of
pulses received at the input providing two simultaneous
information for example flow rate and product quantity
for a given process.
DIRECTION OF ROTATION INDICATION
Direction sensing indication is a matter of simply setting
the totalizer to read UP/DOWN direction (modes PHASE
and dIrEC).
The direction of rotation is denoted by the LED's MAX
and MIN on the left of the display. LED MAX illuminates
when the totalizer counts in the up direction, so it can
be associated to a "positive" rate.
LED MIN illuminates when the totalizer counts down,
which may be associated to a "negative" rate.
A change in the polarity of rate is recognized when the
meter receives at least two consecutive pulses in the
opposite direction of the one of the previous pulses.

5.1. Frequencymeter / Tachometer
CONFIGURATIONS
The different configurations allow measurement of
almost any process quantity based in frequency
calculation.
5.1.1. Frequencymeter
To use this instrument as frequency indicator, select
directly the frequencymeter input.
DECIMAL POINT
The only parameter to select in this input menu is the
position of the decimal point, which can be 0, 1 or 2.
The decimal point position determines the max. and min.
frequencies visible on display; with two decimals, max.
frequency will be 999.99Hz and min. frequency 0.01Hz,
with one decimal, max. frequency will be 9999.9Hz and
min. frequency 0.1Hz, and with no decimal, max.
frequency is limited according to the selected options
(see technical features in page 56) and min. frequency
will be 1Hz.
5.1.2. Tachometer for RPM
In this configuration the meter reads rotational rate in
revolutions per minute (RPM).
The tachometer is configured by entering the number of
pulses per revolution and the decimal point location.
PPR (PULSES PER REVOLUTION)
The PPR parameter is the actual number of pulses that a
sensor connected to a wheel gives to the input of the
meter in a rotation of the wheel.
The method of measurement is based in calculating the
time necessary for the system to produce a complete
rotation of the wheel, therefore, by default each reading
extends over the programmed number of pulses.
DECIMAL POINT
The decimal point location, in combination with a
suitable scale factor allows the display reading be
expressed into other units different from RPM if desired.

5.1.3. Tachometer Rate
In this configuration the meter can be easily scaled to
read direction, speed, flow or time directly in the desired
units by entering only two parameters: Input Frequency
and Desired Display.
DIRECT OR REVERSED SCALING
Direct scaling. The relationship between frequency
and display is directly proportional, that is, the higher the
frequency, the greater the display. This will be the mode
to choose in most applications.
Reversed scaling. The relationship between frequency
and display is reversed, that is, the higher the frequency,
the lower the display. A typical application of this mode
is explained in the example of page 28.
The scaling procedure consists of entering a display
value corresponding to an input value. A straight line
plotted from this point to zero (input=0, display=0)
establishes a linear relationship between frequency and
display.
INPUT FREQUENCY
For scaling purposes, the input frequency value can be
programmed within all range of the display (the
frequency limits are given in page 57 of the present
manual).
The input frequency can be programmed with 0, 1 or 2
decimal places. The decimal point position has value, for
example, a frequency value of 200Hz can be
programmed as 200, 200.0 or 200.00
DESIRED DISPLAY
In this phase it is programmed the display value
corresponding to the programmed input frequency.
The decimal point can be located in any of the digits of
the display to help reading the display in the desired
units.

In this configuration the meter can be easily scaled to
read direction, speed, flow or time directly in the desired
units by entering only two parameters: Input Frequency

EXAMPLE OF SCALING IN RATE MODE
Loaves of bread are transported in a conveyor belt and
introduced in a continuous baking oven. The belt is attached
to a turning shaft of 20cms that gives 6 pulses per revolution.
The average time necessary for a loaf to be baked is 15min
and 30s and it has been determined that, to achieve this time,
the rate of the turning shaft must be kept to 300rpm.
This example allows exposing some capabilities of the rate
meter configuration.
The rate of the turning shaft is 300 revolutions per minute,
which is equal to 5 revolutions per second.
If the turning shaft makes 5 complete revolutions in one
second and each revolution drives out 6 pulses, the total
number of pulses per second is 30. The input frequency is
then 30Hz.
Rate of the conveyor belt (m/s)
The rate of the conveyor belt at the specified frequency is:
rpm * π * diameter = 300 * π * 20 = 18849.6 cm/min which
is in m/s, 3.142m/s.
PARAMETERS TO PROGRAM:
RATE MODE: DIRECT
INPUT FREQUENCY: 30
DESIRED DISPLAY: 03142
DECIMAL POINT: 03.142 (m/s)
Baking Time (min)
It is required to monitor the baking time knowing that, at the
specified frequency of 30Hz, the time taken for each loaf to be
baked is 15min 30s.
When rate (and frequency) grows, the baking time is reduced
proportionally. The rate meter must then be programmed for
reverse mode.
PARAMETERS TO PROGRAM:
RATE MODE: INVERSE
INPUT FREQUENCY: 30
DESIRED DISPLAY: 00155
DECIMAL POINT: 0015.5 (min)
The time values must be programmed in decimal notation.
In the preceding example, a baking time of 15min 30s has been
introduced as a display value of 15.5 (15 minutes and a half).
Daily Production (loaves/day)
It has been determined that, in the specified conditions, the
bread loaves are baked at an average of 10 loaves per minute.
The baking oven works 12 hour per day and it is required to
monitor the production of loaves per day.
Ten loaves per minute is equivalent to 10x60=600 loaves per
hour.
At a frequency of 30Hz, the daily production is 600x24=14400
loaves/day.

5.2. Display Setup
5.2.1. Options of the Process Variable
The menu ProC in the module CndSP contains various parameters for scaling and filtering the display -Scale Factor, Max
and Min Times, Averaging-.
SCALE FACTOR
The scale factor is programmable between 0.0001 and 9999 and multiplicities or divides depending on if it is higher or lower
than 1.
For example, it can be used to change display units, rpm instead of rps.
TIME LIMIT
The time limit, programmable from 1 to 99 seconds, is the amount of time that the meter waits for at least one pulse is
produced at the input before it is considered to be zero.
The time limit is initialized at the reception of each input pulse. If no more pulses are detected before the
time limit runs out, the display is forced to zero.
0.............. 0.............. 0.................... t límite
0............. ......
display=0
Decreasing the limit time makes the instrument respond more quickly to the zero condition when the system stops.
Nevertheless, this reduction also will cut the lowest frequencies (for example: with a time limit of 10s, it would be
impossible to see frequencies under 0.1Hz and with a time of 1s, frequencies under 1Hz).

AVERAGE TIME
The average time is a time interval in seconds during
which all readings calculated from the input are
averaged.
The average time is programmable from 0 to 9.9
seconds.
To disable this feature program 0.
When the display presents unwanted variations, due
to that the input signal is not regular, the
programming of the average time for a larger value
may help stabilize the display.
The average time can be calculated for a desired
number of readings knowing the signal frequency.
Example: With a setup of 0.1s, if the input signal
frequency is of approx. 10Hz or less, the meter will
only take one reading per each 0.1s making no
average. With an input signal of approx. 100Hz, the
meter will be able to collect and average about 10
readings in 0.1s. If the input signal is of approx.
1000Hz, the display will read out the average of
about 100 readings.
30
IMPORTANT: Direction sensing indication is achieved
by selecting one of the bidirectional count modes
PHASE or dIrEC.
"Positive sign" indication occurs when the pulses applied to
the instrument increase the counter while "negative sign"
indication occurs when the input pulses decrement the
counter.
A change in the polarity of rate is recognized when the meter
receives at least two consecutive pulses in the opposite
direction of the one of the previous pulses.
DECIMAL POINT
The decimal point indication helps to read the display in the
desired engineering units.
The decimal point has not real value, that is the digits to the
right of the decimal point are not actually decimals. To read
values with resolution to the desired decimal places is
achieved by a combination of decimal point and scaling
factor.
SCALE FACTOR
The scale factor is programmable from 0.0001 to 99999.
Individual decimal point location makes possible to program
any value within this range independently from the decimal
point of the display. Any number below 1 acts like a divisor
while a number above 1 acts like a multiplier.

the instrument increase the counter while "negative sign"
indication occurs when the input pulses decrement the
counter.
A change in the polarity of rate is recognized when the meter
receives at least two consecutive pulses in the opposite
direction of the one of the previous pulses.
DECIMAL POINT
The decimal point indication helps to read the display in the
desired engineering units.

7. PROGRAM PARAMETERS AND KEYBOARD FUNCTIONS LOCK-OUT
The instrument is supplied with all software programming parameters accessible to operator's modifications. After
completing the software configuration, it is recommended to protect configuration settings by the following steps:
1. Lockout programming parameters to prevent from accidental or unauthorized modifications.
2. Lockout keyboard functions to prevent from accidental or unauthorized modifications.
3. There are two modes to lock-out the program parameters; total or selective. If some parts of the program have to be
adjusted at a later time, make a selective lock. If you don’t need to make changes, make a total lock.
4. The access to the lockout routine is allowed by entering a safety code. At factory this code is set to 0000. We
recommend changing this code, to write it down and keep in a safe place.
TOTAL LOCKOUT
The access to the programming routines to read data is allowed even if all parameters are locked out totLC=1, but it will
not be possible to enter or modify data. In this case, when entering in the programming mode, the display shows the
indication "-dAtA-".
SELECTIVE LOCKOUT
When only some parameters are locked out, all configuration data can be read but only non-protected parameters can
be modified. In such case, when entering in the programming mode, the display shows the indication -Pro-.

Menus or submenus that can be locked out are:
• Setpoint 1 configuration (SEt 1).
• Setpoint 2 configuration (SEt 2).
• Setpoint 3 configuration (SEt 3).
• Setpoint 4 configuration (SEt 4).
• Input configuration (InPut).
• Display (dsp)
• Analog output configuration (Anout).
• Serial output configuration (rSout).
• Logic inputs configuration (LoGIn).
• Lock-out of the reset key, not of the logic function.
• Offset value configuration
• Direct access to the Setpoints value configuration (SEtVAL).
The first four and “SEtVAL” only appear if the corresponding option 2RE, 4RE, 4OP ó 4OPP has been installed, “Anout” will appear
when any of the NMA or NMV options are installed, and “rSout” when any of the RS2 or RS4 options are installed.
7.1 – Security menu diagram
The following figure shows the security menu. In this menu is configured the programming lockout. The access to this menu is
accomplished from the run mode by pressing the
key during 3 seconds, until the "CodE" indication appears.
The instrument is shipped from factory with the following default code: "0000". Once entered this code, the “LISt” indication will
appear, from which we will enter in the parameters lockout. Acceding to the "CHAnG" menu will allow us to enter a personal code,
that we have to write down and keep in a safe place (Do not count on your memory). This personal code makes the default
code useless.
If an incorrect code is entered, the instrument will return automatically to the run mode.
Total lockout programming is achieved changing to 1 the “totLC" variable, changing it to 0, will lead to the selective lockout of the
programming variables. Programming each one of the parameters to 1 will active the lockout, if they are set to 0 programming will
be accessible. Though the programming is locked out, it remains possible to visualise the current programming.
The "StorE" indication informs that the modifications effectuated have been stored correctly.
Menus or submenus that can be locked out are:
• Setpoint 1 configuration (SEt 1).
• Setpoint 2 configuration (SEt 2).
• Setpoint 3 configuration (SEt 3).
• Setpoint 4 configuration (SEt 4).
• Input configuration (InPut).
• Display (dsp)
• Analog output configuration (Anout).
• Serial output configuration (rSout).
• Logic inputs configuration (LoGIn).
• Lock-out of the reset key, not of the logic function.
• Offset value configuration
• Direct access to the Setpoints value configuration (SEtVAL).

9.1 – Setpoints output
9.1.1 – Introduction
An option of 2 or 4 SETPOINTS, programmable within the full display range, can be incorporated to the unit thus providing
alarm and control capabilities by means of individual LED indicators and relay or transistor outputs. All the setpoints
provide independently programmable value, time delay (in seconds), asymmetrical hysteresis (in counts of display) and
selectable HI/LO acting.
The setpoint option consists of a plug-in additional card that once installed to the meter's main board, activates its own
programming module, they are totally configurable by the user and their access can be locked out via software.
These are the control output options available:
2RE: 2 Relays SPDT 8 A
4RE: 4 Relays SPST 5 A
4OP: 4 NPN outputs
4OPP: 4 PNP outputs
These types of outputs, capable of carrying out a wide variety of control operations and processing of limit values,
increases notably the unit's performance qualities thanks to the possibility of combining basic alarm functions with
advanced safety and control applications.

9.1.7 – Description of operation in Frequencymeter, Tachometer mode.
As programmed like independent setpoints, the alarm outputs activate when the display value reaches the userprogrammed value. The independent alarms programming requires definition of the following basic parameters:
b. HI/ LO ACTING MODE.
In HI mode, the output activates when the display value exceeds the setpoint level and in LO mode, the output
activates when the display value falls below the setpoint
c. PROGRAMMABLE TIME DELAY or HYSTERESIS.
Each output action can be deferred by a programmable time delay or hysteresis level.
The time delay is the time that takes the output to activate after passing through the setpoint in the up or down
direction, while the hysteresis band will be selected asymmetrical i.e. only acts on the output deactivation edge.
The delay is programmable in seconds, from 0 to 99.
The hysteresis can be programmed, in counts, within the full display range. The decimal point appears in the same
position as programmed in the display configuration module.
The figures 1 and 2 show the time delay action (dly) and the asymmetrical hysteresis action (hys-1) of two alarms
(SET1 and SET2) programmed to activate in HI mode (OUT1) and LO mode (OUT2)

activates when the display value falls below the setpoint
c. PROGRAMMABLE TIME DELAY or HYSTERESIS.
Each output action can be deferred by a programmable time delay or hysteresis level.
The time delay is the time that takes the output to activate after passing through the setpoint in the up or down
direction, while the hysteresis band will be selected asymmetrical i.e. only acts on the output deactivation edge.
The delay is programmable in seconds, from 0 to 99.
The hysteresis can be programmed, in counts, within the full display range. The decimal point appears in the same
position as programmed in the display configuration module.

9.2 – RS2 / RS4 Output
9.2.1 – Introduction
The RS232C output option consists of an additional card (reference RS2) that is installed in the M2 plug-in connector of
the instrument’s main board. The card incorporates one 4 wires telephone socket with output at the rear of the
instrument.
The RS485 output option consists of an additional card (reference RS4 that is also installed in the M2 plug-in connector of
the instrument’s main board. The card incorporates a 6-pin / 4-contact telephone socked with output at the rear of the
instrument.
The serial output permits to construct a communication line through which a master device can request the transmission
of data such de display value, setpoint values, peak, valley, tare (or offset in case of thermometers) and to perform
operations such as tare of the display, reset of the peak, valley or tare memories and update setpoint values..
The output option is totally software configurable as for the transmission rate (1200, 2400, 4800, 9600 or 19200 Baud),
the instrument’s address (from 00 to 99), the protocol (ASCII, ISO 1745 and MODBUS RTU).
The operating mode is half-duplex and it normally stands in data reception mode until reception of a message.
A valid data transmission may cause the immediate execution of an action (tare, reset of peak, valley or tare memories
modification of setpoint values) or the transmission of a response from the instrument (display value, one of the setpoints
value, peak, valley, tare / offset). Only the display value can be called up via external contact according diagram in page 9
of RS2 manual.
Three communication modes are available; the ASCII mode uses a simple protocol compatible with several DITEL
instruments. The ISO mode, in accordance with the ISO 1745 norm, allows a more effective communication in noisy
environments as it checks the messages validity checking both transmission and reception. And eventually the protocol
MODBUS RTU
As you will see in the functions table, the protocol ASCII uses 1 or 2 bytes according to the command type and the
protocol ISO 1745 imposes the use of two bytes per command.

9.3 ANALOG OUTPUT
9.3.1 – Introduction
Two ranges of analog output (0-10 V and 4-20 mA) can be incorporated to the MICRA D by means of an additional card,
either the NMV card for voltage output or the NMA card for current output, which is installed on the meter's main board via
plug-in connector M3, both cards, cannot be used simultaneously.
The outputs are opto-isolated with respect to the signal input and the power supply.
The optional board provides a two terminal connector [(+) and (-)] that drives out a signal variation from 0 to 10V or from
4mA to 20mA proportional to a user-defined display range.
This way, the meter is furnished with a signal that can be used to control variables and operates at each moment
proportionally to the magnitude of the effect under control.
These signals can also be used to transmit display information to a variety of terminal equipment such as graphic recorders,
controllers, remote displays or other devices that accept input data in analog form.
The instrument will detect the type of option that has been installed and will operate in accordance.
The display values producing the full scale output (OUT-HI and OUT-LO) are also introduced via front-panel buttons in the
same programming module. The analog output then follows the display variation between the HI and LO programmed
points.
The output signal can be set up for reverse action by programming the low display for the high output (OUT-HI) and the
high display for the low output (OUT-LO).
9.3.2 – Installation of NMA or NMV option
Lift out the electronics assembly from the case and use a screwdriver to pull on the junctions between the case and the
grey-marked area to detach it from the case. The so performed orifice will allow the analog output board connector be
brought out at the rear of the instrument. Install the circuit board so that the lower pin fits into the corresponding main
board insertion slot and push down to plug the M3 option connector in the main board M3 location. If the instrument is to be
installed in high vibrating environments, it is recommended to solder the card to the main board making use of the copper
tracks on both sides of the card
p
in and around the main board hole on its solder side.
