5. Typical Applications
To measure frequency signals from low voltage sensors such as NPN, PNP, Namur, pick-up and similar. To
measure frequency signals from ow meters. To measure frequency signals from AC power networks up to 600
V AC. Signal acquisition, linearization and transmission to remote acquisition devices. Isolation between circuits
provided. Ranges can be scaled to the desired range.
6. SOS Mode
The instrument includes a congurable ‘SOS mode’ function that provides a way to manually congure a xed
output signal. This output signal remains xed, independent of the input signal value or sensor state.
This function allows to perform urgent maintenance or repair tasks at the input section of the system, for example
replacing sensors, shunts, or deactivating power lines, while the instrument still provides a controlled signal that
allows for the process to continue its activity, under human surveillance. When the maintenance or repair task
has been performed, the instrument can be taken back to the standard working mode, where the output signal is
proportional to the input.
When manually activated, the ‘SOS mode’ generates the output signal congured, and the front display remains
ashing with the message ‘SoS’. All other systems are disabled, which means that :
• no error messages will be shown on display
• no key ‘UP’ () ‘fast access’ menu is accessible
• no key ‘LE’ () ‘messages’ function is accessible
• no ‘Eco’ mode activates
Only key ‘SQ’ () is accessible, to access the ‘conguration menu’ (eventually this access can be password
locked) in order to deactivate the ‘SOS mode’. Deactivation of ‘SOS mode’ must be performed manually by
conguring the function to ‘oFF’.
To congure the ‘SOS mode’ function, see section 16.9.
7. Messages
The instrument includes a congurable ‘messages’ function that provides advanced system information on the
display, available to the operator with a single click at the front key ‘LE’ ().
This information is helpful during start-up, installation, system verication, routine maintenance and troubleshooting,
as messages and values provide information on the actual input and output signal value, actual percentage of the
input signal compared to the full scale and scaled process values.
This information is available at any time, and is displayed sequentially when requested. Access to this information
reduces maintenance time, improves time invested in failure location, and helps for an easy resolution of the
problem.
Additionally, each instrument can be assigned a custom label code of up to 8 characters (see Table 1), that can
be displayed at the front display or at the messages sequence, making system identication of each instrument
an easy task.
To congure the ‘messages’ function, see section 16.8.

8. Predefined Configuration Codes
Select the desired code for your application, and check the wing sections for more information:
• for information on how to activate a code, see section 16.1
• to customize the input and output signals, see section 16.5
• Predened conguration codes do no affect the sensor conguration.
• Code ‘uSEr’ indicates that a user custom conguration is active, and it does not match any of the listed codes.
This code is non-selectable, for information only.
Example: select code ‘025’ for 0/100 Hz=4/20 mA, the instrument reads code ‘025’. Later, congure the input to
0/950 Hz = 4/20 mA, this does not match a listed code, and the instrument reads ‘uSEr’. Or change the output to
0/100 Hz = 1/5 V DC, this does not match a listed code, and the instrument reads ‘uSEr’.
• Code ‘---’ identies the end of the list, it follows code ‘199’ and the list with code ‘010’. Select ‘---’ exits the
‘conguration menu’ without applying changes.

10. Reading Channels
Reading channels ‘A’ and ‘B’ have different frequency bandwidths and different detection levels. Each ‘Predened
sensor’ has a channel, assigned by default, although the channel can also be manually congured (see section
16.2). Below are the characteristics of each channel.
Channel ‘A’
• has a ‘zero crossing’ type of detection
• has a bandwidth limit of 80 KHz (with gain ‘x1’) and 30 KHz (with gain ‘x100’). Maximum frequencies for each
type of sensor are listed at ‘Table 3’.
• has a congurable gain of ‘x1’ or ‘x100’, available to signals connected at terminals ‘1, 2, 3’. Use the ‘x100’
gain to work with pick-up signals with at least 10 mVpp.
Channel ‘B’
• has signal detection levels at approximately ‘<1 V’ and ‘>2 V’, which provides a higher noise immunity when
compared to channel ‘A’.
• has a bandwidth limit of 1 MHz.
• is the default channel for all sensors, except V AC and pick-up.

12.2. ‘Normal Mode’ of Operation
AT POWER-UP
When the power supply is connected, the instrument applies the following sequence :
• the ‘display’ shows the rmware code ‘b4.xx’.
• the ‘display’ shows the congured ‘sensor’, ‘input range’ and ‘units’, (for example: ‘SEnSor nPn’, ‘1.000’ and
‘KHz’).
• the instrument is now in ‘normal mode’ of operation and the ‘display’ shows the ‘information’ congured
at section 16.6.
FROM ‘NORMAL MODE’ OF OPERATION
From ‘normal mode’ of operation, the operator can access the following functions:
• key ‘SQ’ () gives access to the ‘conguration menu’ (see section 12.3).
• key ‘UP’ () gives access to the ‘force’ menu (see section 12.4).
9How to Operate the Instrument
Page 10
• key ‘LE’ () activates the ‘messages’ function (see section 12.5).
‘ECO’ FUNCTION (‘DISPLAY’ POWERED OFF)
The ‘Eco’ function powers off the display under the following conditions:
• the instrument is in ‘normal mode’ of operation.
• there is no interaction from the operator for 60 seconds.
The decimal point remains active (ashing), indicating that the instrument is working correctly. This is a
congurable function, enabled by default. To congure the ‘Eco’ function, see section 16.9.
Table 7 | ‘ECO’ Decimal Point
12.3. How to Operate the Configuration Menu
HOW TO ENTER THE ‘CONFIGURATION MENU’
With the instrument in ‘normal mode’ of operation (see section 12.2), press the ‘SQ’ () key and maintain for 1
second. The horizontal LEDs light from bottom to top. When the upper led lights, the instrument enters into the
‘conguration menu’.
When entering the ‘conguration menu’, the rst menu entry ‘Function code’ (codE) is displayed. See section
17 for a full view of the ‘conguration menu’.
If the ‘SQ’ () key is released before entering into the ‘conguration menu’, the horizontal LEDs light
downwards from top to bottom, and the instrument returns to ‘normal mode’ of operation.
HOW TO OPERATE INSIDE THE ‘CONFIGURATION MENU’
Inside the ‘conguration menu’, use the front keypad to move through menu entries, parameters, and select
conguration values:
• Key ‘SQ’ () functions as the ‘ENTER’ key. It selects the menu entry currently displayed. At numerical value
entries, it validates the number displayed.
• Key ‘UP’ () moves vertically through the different menu entries. At numerical value entries, it modies the
selected digit by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. The most signicant digit has additional values
‘-’ and ‘-1’.
• Key ‘LE’ () functions as the ‘ESCAPE’ key. It leaves the selected menu entry, and eventually, will leave
the ‘conguration menu’. When leaving the ‘conguration menu’, the changed parameters are activated. At
numerical value entries, the ‘LE’ () key allows to select the active digit. To modify a numeric value press the
‘UP’ () key to increase the value ‘+1’. Press the ‘SQ’ () key to validate the value.
WHEN EXITING THE ‘CONFIGURATION MENU’
When exiting the ‘conguration menu’ without changes (either by ‘rollback’ activation or because there are no
changes in the conguration), the horizontal LEDs light down from top to bottom, and the instrument returns to
‘normal mode’ of operation.
When exiting the ‘conguration menu’ with changes, the display LEDs light a round shape while the new
conguration is stored. When the round shape is nished, a start-up is applied (see section 12.2). After startup, the new conguration is active and the instrument is in ‘normal mode’ of operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument exits the ‘conguration menu’
discarding changes, and returns to ‘normal mode’ of operation.
Important: When the operator is inside the ‘conguration menu’, the output signal will remain overranged at
maximum signal. Additional congurations are available at the ‘On ‘Sq’’ parameter (see section 16.9).
When the operator exits the ‘conguration menu’, the output signal is temporarily set to minimum value for a
time <5 seconds, while the instrument restarts.

12.4. How to Operate the ‘Force’ Menu
HOW TO ENTER THE ‘FORCE’ MENU
With the instrument in ‘normal mode’ of operation (see section 12.2), press and hold the ‘UP’ () key for 1
second. The horizontal LEDs light from bottom to top. When the upper led lights, the instrument enters into the
‘force’ menu.
If the ‘UP’ () key is released before entering into the ‘force’ menu, the horizontal LEDs light downwards from
top to bottom, and the instrument returns to ‘normal mode’ of operation.
HOW TO OPERATE INSIDE THE ‘FORCE’ MENU
The available functions inside the ‘force’ menu can be congured (see section 16.7). By default, ‘Force high’,
‘Force low’ and ‘Force set’ are available. Inside the ‘force’ menu:
• press the ‘UP’ () key to move to the next function.
• press the ‘SQ’ () key to activate the selected function.
When the function is active, the display will remain ashing. Press the ‘SQ’ () key to deactivate the function
(display stops ashing), or wait for the rollback to activate.
Table 8 | Example of ‘Force’ menu with all functions set to ‘on’
See section 16.7 for a list and a description of available functions
DESCRIPTION OF ‘FORCE’ FUNCTIONS
The ‘force’ functions allow to manually force the output signal to the low and high levels of the output signal
selected. These functions allow to easily validate the correct function of remote elements connected to the
instrument output, such as PLC, HMI’s, SCADAs, etc.
The ‘force low’ function sets the output signal to the minimum value of the selected range (4 mA or 0 V DC or
the value congured at the ‘output_ low’ parameter).
The ‘force high’ function sets the output signal to the maximum value of the selected range (20 mA or 10 V DC
or the value congured at the ‘output_high’ parameter).
The ‘force set’ function sets the output signal to a value between 0 and 100% of the maximum selected range
(4 to 20 mA or 0 to 10 V DC or the range congured at the ‘output_low’ and ‘output_high’ parameters). When
entering the ‘force set’ function, the display reads ‘50’ (the output is forced to 50% of the congured range).
Use keys ‘UP’ () and ‘LE’ () to move up to 100% or down to 0% of the congured range.
HOW TO EXIT ‘FORCE’ MENU
To exit the ‘force’ menu, press the ‘LE’ () key, or press the key ‘UP’ () key until the parameter ‘---’ appears,
and select by pressing the ‘SQ’ () key, or wait without pressing any key until the automatic ‘rollback’
activates.
When exiting the ‘force’ menu, the horizontal LEDs light down from top to bottom, and the instrument returns to
‘normal mode’ of operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument exits the ‘force’ menu and returns to
‘normal mode’ of operation.”

12.5. How to Activate the ‘Messages’ Function
HOW TO ACTIVATE ‘MESSAGES’ FUNCTION
With the instrument in ‘normal mode’ of operation (see section 12.2), press the ‘LE’ () key to activate
the ‘messages’ function. The ‘messages’ function displays information about the instrument. The
information available is congurable (see section 16.8).
The ‘messages’ function ends when all the information has been displayed or front keys ‘UP’ () or ‘SQ’ ()
are pressed. The ‘display’ returns to ‘normal mode’ of operation.
12.6. Fast and Advanced Configurations
FAST CONFIGURATION
The fastest way to congure the instrument is to activate one of the predened conguration codes (see
section 8) and predened sensors (see section 9).
Access the ‘conguration menu’ and enter the ‘Function code’ (codE) menu entry. The code displayed is the
current active input - output range. Select the new code and validate. Selecting a code automat exits the
‘conguration menu’ and activates the new conguration.
Important: There are different codes for 4/20 mA and 0/10 V DC output signals.
Access the ‘conguration menu’ and enter the ‘Predened sensors’ (SnSr) menu entry. The sensor displays the
actual congured sensor. Select the desired sensor and validate.
To customize the input and output signals, see the ‘Advanced scaling’ section of the ‘conguration menu’ (see
section 16.5).
To customize the sensor parameters, see the ‘Sensor conguration’ section of the ‘conguration menu’ (see
section 16.2).
ADVANCED CONFIGURATION
Additional conguration parameters are available at the ‘conguration menu’. The operator can customize the
input and output signal ranges, sensor parameters, the message seen on display, the functions available at
the ‘force’ menu, the messages associated to the ‘LE’ () key, activate lters, password function, etc.
See section 16 for a detailed explanation on the ‘conguration menu’.”
13. Input Signals
13.1. Low Voltage Frequency Signals
SIGNALS ACCEPTED
The instrument can be congured to measure frequency from typical impulse sensors, such as NPN, PNP,
pick-up, push-pull, mechanical contact, reed contact, Namur and similar.
The instrument parameters allow to congure pull-up and pull-down resistors, apply signal amplication for
very low voltage signal, modify the trigger level, apply anti-rebound lters, and congure the voltage to power
the sensor.
Although there is a dedicated menu entry for most popular sensor types, the operator can manually congure
the mentioned parameters as needed, as explained in section ‘16.2’.
PREDEFINED CONFIGURATION CODES
See ‘Table 2’ for a list of predened conguration codes for input-output signal ranges. To activate a code see
section 16.1.
CUSTOMIZED SIGNAL RANGES
To customize the input and / or output signal ranges, access the ‘Advanced scaling’ menu (see section 16.5).
ACCURACY AND FREQUENCY LIMITS
Accuracy depends on the calculation mode (see section 15). Maximum frequency depends on the sensor (see
Table 3).
TRIGGER LEVELS
When directed through reading channel ‘B’ (see section 10), a typical value for level detection is ‘0’ below 1 V
DC, and ‘1’ above 2 V DC. Operate the ‘Trigger level’ parameter (see section 16.2) to empirically move up and
down the trigger levels. The limit trigger level are approximately 0.5 V DC and 3 V DC.
Pick-up signals are typically channeled through channel ‘A’ and signal is detected as a ‘0 crossing.’ Trigger
levels can help improve noise immunity.
12DR-I4F User's Manual
Page 13
13.2. V AC Frequency Signals
SIGNALS ACCEPTED
The instrument has a dedicated input to read frequency from voltages up to 600 V AC and voltages up to 60
V AC. Phase-to-phase and phase-to-neutral connections are accepted.
PREDEFINED CONFIGURATION CODES
See ‘Table 2’ for a list of predened conguration codes for input-output signal ranges. To activate a code see
section 16.1.
CUSTOMIZED SIGNAL RANGES
To customize the input and / or output signal ranges, access the ‘Advanced scaling’ menu (see section 16.5).
ACCURACY AND MAXIMUM FREQUENCY
Accuracy depends on the calculation mode (see section 15). Maximum frequency depends on the sensor (see
Table 3).
TRIGGER LEVELS
AC signals are channeled through channel ‘A’ and signal is detected as a ‘0 crossing’. Trigger levels can help
improve noise immunity around ‘0’.
MINIMUM AMPLITUDE LEVELS
The minimum voltage levels recommended are 30 V AC for the 600 V AC range, and 6 V AC for the 60 V AC
range. Signals with amplitude levels below 6 V AC, should be channeled as ‘low voltage’ input signals (see
section 13.1).
Table 9 | Connection Examples for V AC <600 V AC and < 60 V AC Signals
Important: Terminal 4 and terminal 1 are internally connected. Connecting dangerous voltages to terminal 4
makes terminal 1 a terminal with dangerous voltage.

15. Frequency Calculation Modes
The instrument calculates the frequency applying the ‘slow’ mode or the ‘fast’ mode.
Fast mode
‘Fast’ mode activates when the ‘input high signal’ parameter (see section 16.5) is higher or equal than 500 Hz.
The frequency calculated is the number of impulses received during a time window, divided by the time window
value in seconds. The time window is congured at the ‘Gate’ (GAtE) parameter (see section 16.2) with available
values ‘0.5’, ‘1.0’, ‘2.0 and ‘4.0’ seconds.
The frequency value is calculated at the end of each time window.
Slow mode
‘Slow’ mode activates when the ‘input high signal’ parameter is below 500 Hz.
The frequency calculated is the inverse of the time between impulses. The value is calculated and updated every
time an impulse is detected.
Measured frequency is ‘0’ when the time between impulses is higher than the value congured at the ‘time_to_0’
(tt0) parameter (values between ‘1.0’ and ‘10.0’ seconds). Once the reading has dropped to ‘0 ’, the instrument
needs 2 impulses to measure a new frequency.
Ranges below 500 Hz can also be manually set to ‘fast’ mode if needed (see section 16.2). Parameters not
available in the active mode ill show ‘-nA-’ when accessing their value at the conguration menu.

16. Configuration Menu
16.1. Function Codes and Sensor
The fastest way to congure the instrument, is to select a
predened conguration code (see Table 2) and a predened
sensor (see Table 3). At the ‘Conguration code’ (codE)
parameter use keys ‘UP’ () and ‘LE’ () to move up and
down through the list of codes. Locate the desired code, and
press ‘SQ’ (). The instrument shows the ‘codE’ parameter.
Press ‘LE’ () to exit the ‘conguration menu’. The instrument
stores the new conguration, applies a ‘power-up’ routine and
returns to the ‘normal mode’ of operation (see section 12.2).
Selecting a ‘reserved’ code performs no action. Selecting ‘---’
exits the ‘conguration menu’ without applying changes.
When checking the ‘Function code’ (codE) parameter,
the active ‘conguration code’ is displayed. If the actual
conguration does not match any of the conguration codes,
code ‘uSEr’ is displayed.
There are different codes for 4/20 mA output (codes from 010
to 099) and 0/10 V DC output (codes from 110 to 199) (see
section 8).
To customize the input signal range, see the ‘Advanced
scaling’ section of the ‘conguration menu’ (see section 16.5).
At the ‘Predened sensors’ (SnSr) menu, select one of the
predened sensors. Once the sensor is congured, the
instrument is ready to work. The selection congures the
sensor according to ‘Table 3’ (see section 14) and updates
the parameters at the ‘Advanced sensor conguration’ (Ad.Sn) menu. The actual sensor is displayed, and when the actual
conguration does not match any of the predened sensors,
then ‘uSEr’ is displayed.
Important: If the output signal is xed to 4 mA or 0 V DC, and does not change according to the frequency at
the input, then the input frequency detected is 0 Hz, and probably the predened sensor conguration is not
suitable for your sensor. A manual conguration of the sensor may be needed. See section 16.2 on how to
manually congure the sensor parameters.
17Conguration Menu
Page 18
16.2. Sensor Configuration
Sensor conguration is a critical part of the
conguration. If the sensor is correctly congured,
the instrument will be able to read impulses. If the
sensor is not correctly congured, the instrument will
not be able to read any impulse signal and it will be
considered a 0 Hz signal.
• Parameters at the ‘Advanced sensor conguration’
(Ad.Sn), reect the conguration of the ‘Predened sensors’ (SnSr) selection.
• Changing the parameters at the ‘Advanced sensor conguration’ (Ad. Sn) menu, will set
the ‘Predened sensors’ (SnSr) value to ‘uSEr’
(‘User sensor conguration’) meaning that the
actual conguration does not match any of the
predened sensor congurations (see Table 3).
• At the ‘Pull resistors’ (PuL.r) parameter select the
activation or deactivation of pull-up and pulldown resistors.
• select ‘P.uP ’ to activate the pull-up resistor
• select ‘P.dn’ to activate the pull-down resistor
• select ‘nonE’ to deactivate the pull-up and pull down resistors
• At the ‘Gain amplication’ (GAIn) parameter select
the gain of the input signal . Gain applies only to
signals through channel ‘A’ and connected to
terminals ‘123’.
• select ‘G__1’ to activate the gain ‘1’. Usual
gain for V DC signals, that are correctly
detected operating the ‘trigger level’.
• select ‘G100’ to activate the gain ‘100’. Use this
gain for low voltage signals, in the range of mV,
that can not be detected by operating the
‘trigger level’ parameter to its lower value.
At the ‘Trigger level’ (trIG) parameter select empirically
the ‘trigger level’ at a level between ‘0’ and ‘31’. Default
value is ‘15’. Press key ‘UP’ () to increase the value, and
key ‘LE’ () to decrease the value.
• to help you identify the appropriate trigger level,
the vertical led at the left of the display is placed
at the bottom when the signal detected is ‘0’, and
is placed at the top when the signal detected is ‘1’.
Change the state of your input signal, and check
the status of the led to know if the instrument is
detecting the changes at the input.
At the ‘Antirrebound lter’ (rbnd) parameter select a
time value from ‘0’ to ‘1000’ expressed in milliseconds.
After a valid impulse has been detected, the detection
of new impulses is disables for the duration of the
congured time. Use this parameter to prevent detection
of rebounds. A ‘100’ milliseconds value is considered a
standard value to prevent rebounds when working with
mechanical contacts. Applies only in ‘slow mode’ (see
section 15).
At the ‘Excitation voltage’ (V.Exc) parameter select the
value of the excitation voltage. Select +15 V DC (15 V),
select +8.2 V DC (8.2V) for Namur sensors, select +5
V DC (5 V) for TTL or select oFF (oFF) to disable the
excitation voltage.
At the ‘Reading channel’ (chL) parameter select the
channel ‘A’ or ‘B’ to read the signal (see section 10).
At the ‘Working mode’ (ModE) parameter select the frequency calculation mode (see section 15).
18DR-I4F User's Manual
Page 19
At the ‘Gate’ (GAtE) parameter congure the value to ‘0.25’, ‘0.50’, ‘ 1.0’, ‘2.0’ or ‘4.0’ seconds. Applies only in
‘fast’ mode (see section 15).
At the ‘Time to 0’ (tt0) parameter congure a value between ‘1.0’ and ‘10.0’ seconds. Applies only in ‘slow
mode’ (see section 15). Default value is 1 second.
At the ‘Number of imp.’ (nUMb) parameter congure a value between ‘1’ and ‘32’. Applies only in ‘slow mode’
(see section 15). Dene the number of impulses needed to calculate the frequency (default value ‘1’). ’ to wait
for 4 impulses, and then calculate the mean frequency value of the set of 4 impulses.
16.3. Input Range
At the ‘Input range’ (InP) menu entry select the input signal range to
activate.
Important: If you have already selected a conguration code (see section
16.1), the input range has been already selected and there is no need to
manually congure again at the ‘Input range’ (InP) menu entry.
Input signal ranges can also be activated through the ‘predened
conguration codes’ (see Table 2).
All input signal ranges can be congured to a reduced input signal range
by conguring the ‘Advanced scaling’ (Ad.Sc) parameters (see section 16.5).
• Example: select the ‘1 KHz ’ input range and to customize to a smaller
example 0/750 Hz or 250/750 Hz) see section 16.5 and operate each
parameter.
19Conguration Menu
Page 20
16.4. Output Range
At the ‘Output range’ (out) menu entry, select the output signal range to 4/20 mA
(value ‘420’) or to 0/10 V DC (value ‘010’).
The output signal range selected can be later customized to operate in a reduced
range of signal (see section 16.5).
16.5. Advanced Scaling
At the ‘Advanced scaling’ (Ad.Sc) menu, the input
and output signal ranges can be customized.
The parameters inside this menu represent the
real input and output signal ranges congured
at the instrument. When selecting a ‘predened
conguration code’, these parameters are
congured according to the code selected. The
parameters listed below, are accessible for
manual conguration:
• at the ‘Input units’ (unIt) parameter
congure the units for the input signal
parameters, between ‘Input units in Hz’
(hrZ), ‘Input units in KHz’ (KhrZ) and ‘Input units in MHz’ (MhrZ).
• at the ‘Input low signal’ (In.Lo) parameter
congure the low input signal value. Units
expressed as congured at the ‘Input units’
(unIt) parameter, with 1 decimal point.
• at the ‘Input high signal’ (In.hI) parameter
congure the high input signal value. Units
expressed as congured at the ‘Input units’
(unIt) parameter, with 1 decimal point.
• at the ‘Output low signal’ (ou.Lo) parameter
congure the low output signal value. Units
expressed in V DC o mA, , with 2 decimal
points.
• at the ‘Output high signal’ (ou.hI) parameter
congure the high output signal value. Units
expressed in V DC o mA, , with 2 decimal
points.
These ve parameters dene the relation
between the input and the output signal (see
Table 12), and can be modied independently, to
match the specic input-output relation for your
application (see Table 12). Additionally, a process
value can be scaled using the last three
parameters of the ‘Advanced Scaling’ (Ad.Sc) menu entry. The scaled process value
can be accessed through the ‘display
information’ function (see section 16.6) or
the ‘messages’ function (see section 16.8).
• at the ‘Process low’ (Pr.Lo) parameter,
congure the process value
associated to the low input signal
value.
• at the ‘Process high’ (Pr.hI) parameter,
congure the process value
associated to the high input signal
value.”
• at the ‘Process decimal point’ (Pr.
dP) parameter, congure the decimal
point position for the process value.
Example: a 0/1000 Hz signal from is
associated to a 0/150.0 RPM process
value. Congure the process value to ‘0’
and ‘150.0’ (‘Process low’ = ‘0’, ‘Process
high’=‘1500’, ‘Process decimal poin
process value in RPM can be displayed at
the front display.
