controllers, offering exceptional performance.
The strain gage meter is front panel programmable to accept unipolar and
bipolar DC voltage inputs and 0-20 or 4-20 mAdc inputs. The meter will
accept inputs from most of the process sensors in use today such as
transmitters, pressure transducers, and potentiometers.
Configuring the meter is accomplished through the 5 front panel buttons. If
the RS-232 or RS-485 communication option is installed, the user may
remotely set the display parameters.
Options for the meter include analog and BCD outputs, relay outputs, and
RS-232 or RS-485 communications.

3.1 SAFETY CONSIDERATIONS
This device is marked with the international caution symbol. It is important to read
this manual before installing or commissioning this device as it contains important
information relating to Safety and EMC (Electromagnetic Compatibility).
Unpacking & Inspection
Unpack the instrument and inspect for obvious shipping damage. Do not attempt to
operate the unit if damage is found.
This instrument is a panel mount device protected in accordance with Class I of EN
61010 (115/230 AC power connections), Class III for the DC power option (10-32Vdc).
Installation of this instrument should be done by Qualified personnel. In order to ensure
safe operation, the following instructions should be followed.
This instrument has no power-on switch. An external switch or circuit-breaker shall be included
in the building installation as a disconnecting device. It shall be marked to indicate this function,
and it shall be in close proximity to the equipment within easy reach of the operator. The switch or
circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it shall meet the
relevant requirements of IEC 94 –1 and IEC 94 -3 (International Electrotechnical Commission).
The switch shall not be incorporated in the mains supply cord.
Furthermore, to provide protection against excessive energy being drawn from the
mains supply in case of a fault in the equipment, an overcurrent protection device shall
be installed.
• The Protective Conductor must be connected for safety reasons. Check that the
power cable has the proper Earth wire, and it is properly connected. It is not safe
to operate this unit without the Protective Conductor Terminal connected.
Conductor Terminal connected.
• Do not exceed voltage rating on the label located on the top of the instrument
housing.
• Always disconnect power before changing signal and power connections.
• Do not use this instrument on a work bench without its case for safety reasons.
• Do not operate this instrument in flammable or explosive atmospheres.
• Do not expose this instrument to rain or moisture.
• Unit mounting should allow for adequate ventilation to ensure instrument does
not exceed operating temperature rating.
• Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to
minimize electrical shock hazards.
EMC Considerations
• Whenever EMC is an issue, always use shielded cables.
• Never run signal and power wires in the same conduit.
• Use signal wire connections with twisted-pair cables.
• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems
persist.
Failure to follow all instructions and warnings may result in injury!

sequentially recalls the previous setpoint settings to the display.
After the ‘MIN’ and ‘MAX’ buttons are used to alter those
values as desired, pressing the ‘SETPTS’ button, again, stores
these new values.
Unless the ‘SETPTS’ button is pressed, each of the four setpoint
values is displayed for approximately 10 seconds after the last
press of the ‘SETPTS’ button. Holding the ‘SETPTS’ button
depressed stalls this automatic sequence, retaining the most
recent setpoint number on the display.

ITEM DESCRIPTION
4/MAX BUTTON
During run mode, pressing this button displays the “HI RDG”
(peak reading) value that has occurred up to the moment the
‘MAX’ button is pressed. This peak reading flashes, to
distinguish its value from the current readings. Since this is a
dynamic peak reading, the value will change if the value
increases while reviewing it.
To return to display of the current readings without resetting the
peak-value memory to zero (0), press the ‘MAX’ button once
again.
To reset the peak-value memory (start a new peak determining
period), press the ‘RESET’ button once.
During the configuration mode, the ‘MAX’ button is used to
change the numerical value of the flashing digit displayed. For
submenu items, such as “L1C.1=0”, pressing the ‘MAX’ button
toggles the choice from “0” to “1”.
The meter allows rapid changes of a displayed numerical value
by making “0” the first value to occur when the ‘MAX’ button is
pressed. After that, the numbers increase to “9” and then roll
over to “0” again. A negative (“–”) symbol may be displayed in
the most significant digit (i.e. the digit at the far left such as
shown here “–.8.8.8.8.8.”)
In the SETPT (SETPOINT) mode (SP1, SP2, etc), pressing the
‘MAX’ button causes the flashing digit to increment by 1 from 0
to 9.
5 /MIN BUTTON
During run mode, pressing the ‘MIN’ button recalls the “LO
RDG” (valley reading) measured since the last press of the
‘RESET’ button. This lowest value flashes, to distinguish it from
the current process display. Since this is a dynamic valley
reading, the value will change if the value decreases while
reviewing it.

ITEM DESCRIPTION
To return to the actual process display, without resetting the low-
value memory, press the ‘MIN’ button once again.
To reset the memory for current-value readings (start a new
observation period), press the ‘RESET’ button once and the
meter will return to the run mode.
In the configuration mode, once in a submenu (like input type)
the ‘MIN’ button allows you scroll through the available choices
such as, 0-20 mA or 4-20 mA, etc.
In the SETPT mode, the ‘MIN’ button advances the flashing digit
to the right.
6MENU BUTTON
In the run mode, this button terminates the measurement
process and allows you to enter the configuration mode,
advancing through the configuration menus.
In the configuration mode, this button will store changes in the
non-volatile memory at the same time advancing the display to
the next menu item.
RESET BUTTON
In the run mode, pressing the ‘RESET’ button once erases the
memories of peak (“HI RDG”), valley (“LO RDG”), and ALARM
latches. The display then returns to the run mode.
WARNING: Pressing the ‘RESET’ button two (2) times will
result in a hard reset of the meter. This will clear the Peak &
Valley, Alarm latches and meter reading and immediately begin
a new measurement.
In the configuration mode, pressing the ‘RESET’ button once,
displays the previous selection. For example, if you were in
“IN CNF” then pressed the ‘RESET’ button once, the display will
then show “RD.SC.OF”. Press the ‘RESET’ button two times to
return to the run mode.
