3. PRODUCT INTRODUCTION
These UL-certified digital panel meters are versatile, cost effective solutions to a wide variety
of monitoring and control applications. Depending on the choice of signal conditioner, they are
easily set up for an accurate display of temperature, pressure, flow, weight, voltage or current,
all in appropriate engineering units and with zero and span adjustment when needed. Setup
can be via front panel pushbuttons or RS232/RS485. Selective security lockout of the front
panel keys protects against accidental changes to meter setup.
High read rates up to 60 per second (50 for 50 Hz operation) are made possible by Concurrent
Slope Conversion (Pat 5,262,780), which integrates the signal over an AC power line cycle for
maximum noise rejection. High read rates provide accurate peak and valley capture, and quick
response for control applications. An adaptive digital filter supplies a time constant for the
encountered signal noise level, yet responds rapidly to changes that exceed a selected
threshold. Self-calibration occurs automatically after every 17th reading.
The standard power supply is a high-efficiency switching unit that operates from AC or DC,
and allows the meters to be powered from worldwide AC without changes. A low-voltage
supply is optional for power from 10-48V batteries or 10-34 Vac. Both supplies provide an
isolated 5, 10 or 24Vdc transducer excitation output .
The meter case conforms to the 1/8 DIN size standard. It is made of high impact, 94V-0 UL-
rated plastic and is watertight to NEMA-4 (IP65) when panel mounted. Mounting is from the
front of the panel and requires less than 110 mm behind the panel. Power and signal wiring is
via removable plugs conforming to UL61010C safety standards. All output options are isolated
from meter and power ground to 250 Vac.
Extended meter versions can linearize nonlinear inputs. Up to 240 data points may be
linearized by a computer program that stores setup parameters in nonvolatile memory.
Extended meters can also display rate of change. For example, they can display flow based on
changing tank level.
Alarm or setpoint control is made possible by two optional Form C mechanical relays (8A at
250 Vac) or two Form A solid state relays. The setpoints may be latching or non-latching, and
may be configured to be energized above or below the setpoint or in a fail-safe mode. The
relays can operate from the filtered signal to reduce relay chatter or from the unfiltered signal
for fastest response. Snubber circuits and a programmable relay switching time delay extend
relay contact life.
An isolated analog output of 4-20 mA or 0-10V is available with an optional analog output
board. The output is linearized to the display, and can operate from the filtered or unfiltered
signal input. It can be scaled via front panel pushbuttons or RS232/RS485.
Communications options available with Series 2 include RS232 or RS485 I/O, and parallel
BCD output. Serial communications can utilize a custom ASCII protocol or Modbus protocol
compliant with the Modbus Over Serial Line Specification V1.0 (2002) for 2-wire, half-duplex
connection. This includes RTU or ASCII modes, up to 247 digital addresses, and up to 32
devices per RS485 line without a repeater.
Computer-aided meter programming using special Setup Software is available for use with the
RS232 and RS485 serial interfaces.

Note: Corresponding main board and option board connectors have the same number of
electrical lines. When an option board is correctly installed, the top and bottom edges of the
main board and option board are aligned.
REASSEMBLING YOUR METER
Slide the electronics assembly into the case until the display board is seated flush against
the front overlay. Insert the bottom tabs of the rear panel into the case, then carefully align
the board connectors with the openings in the rear panel. If necessary, remove any rear
panel knockouts for new option boards that may have been installed. Ensure that all option
boards are properly aligned with the molded board retaining pins on the inside of the rear
panel. Once the rear panel is in place, reinstall the input/output screw clamp terminal plugs.
PANEL MOUNTING
Ensure that the panel mounted gasket is in place against the back of the bezel. Turn the two
mounting screws counterclockwise until the space between the mounting pawl and the rear
of the gasket is greater than the panel thickness. Insert the meter in the panel cutout. Turn
the mounting screws clockwise until the meter is securely mounted in the panel. Do not
overtighten.

8. FRONT PANEL SETUP KEYS
Meter Front Panel
There are four front panel keys, which change function for the Run Mode and Menu Mode,
effectively becoming eight keys. The keys are labeled with alphanumeric captions (MENU,
PEAK, RESET, ALARMS) for the Run Mode and with symbols ( right arrow, right
triangle, up triangle, left arrow) for the Menu Mode.
FRONT PANEL LOCKOUT
The Menu Mode will not work with most meters as received from the factory, since all menu
items have been disabled in software and a lockout jumper is in place. That jumper needs to
be removed for the Menu Mode to work, and menu items under Loc 1, Loc 2 and Loc 3 then
need to be set to "0" via the front panel for these menu items to be unlocked See Section 9.
The paragraphs below assume that all menu items have been unlocked.
MENU MODE KEY ACTION
In the Menu Mode, pressing a key momentarily advances to the next menu item. Holding
down a key automatically advances through multiple menu items for fast menu navigation.
KEYS IN RUN MODE
MENU Key. Pressing MENU from the Run Mode enters the Menu Mode. Pressing
MENU repeatedly will step the meter through the various menu items (if these have not
been locked out) and then back to the Run Mode.
PEAK Key. Pressing PEAK normally causes the peak value of the input signal to be
displayed. The peak display then blinks to differentiate it from the normal present value
display. Pressing PEAK again will return the display to the present value. The PEAK key
can also be programmed to display Valley, to display alternating Peak or Valley, or to
Tare the reading to zero. When Peak or Valley is selected, periodic horizontals bars at
the top of the display indicate Peak, and periodic horizontals bars at the bottom indicate
Valley.
RESET Key. Pressing RESET with PEAK resets peak and valley values. Pressing
RESET with ALARMS resets latched alarms. Pressing RESET with MENU performs a
meter reset (same as power on). Meter reset can also be applied via a rear panel
connect or a serial ASCII command.
11

ALARMS Key. Pressing ALARMS once displays the setpoint for Alarm 1. Pressing it
again displays the setpoint for Alarm 2. Pressing it again returns to the present value.
KEYS IN MENU MODE
Right Arrow Key (MENU). Pressing steps the meter through all menu items that
have been enabled and then back to the Run Mode. With the DC signal conditioner
board and no option boards, available menu items are _InPut, SEtuP, ConFG, _FiLtr,
dEc.Pt,SCALE,OFFst,Loc 1,Loc 2,Loc 3. If a change has been made to a menu
item, that change is saved to non-volatile memory when the key is pressed next,
and StoreE is displayed briefly.
Right Triangle Key (Digit Select).
•Pressing from the InPut menu brings up all meter functions available with the
meter's signal conditioner. For the DC signal conditioner, these are _dC U, _dC A
and _rAtio.
•Pressing from the SEtuP, ConfFG, FiLtr, SCALE, OFFSt, Loc 1, Loc 2 or Loc 3
menus items sequentially selects digit positions 1 - 5, as indicated by a flashing digit:
00000,00000,00000,00000,00000.
•Pressing from the dEC.Pt menu item sequentially selects decimal point positions,
which will flash: d.dddd dd.ddd ddd.dd dddd.d ddddd. .ddddd.
Up Triangle Key (Value Select). Pressing for a flashing item (digit position or
decimal point position) will increment that item. Pressing MENU will save any changes.
Left Arrow Key (Reverse Menu). Pressing has the same effect as the MENU key,
except that menu items are brought up in reverse order.
12

9. ENABLING & LOCKING OUT MENU ITEMS
For security reasons and ease of meter operation, any and all menu
items may be disabled or "locked out" so that they are no longer
directly accessible from the front panel. Each function to be disabled
is set to "1" in menu items Loc 1, Loc 2 or Loc 3, and each function
to be enabled is set to "0." The top menu items Loc 1, Loc 2 and Loc
3 can in turn be locked out by installing an internal hardware jumper.
With the jumper installed, the operator only has access only to
enabled menu items. With the jumper removed, the operator also
has access to menu items Loc 1, Loc 2 and Loc 3.
SETTING HARDWARE LOCKOUT JUMPER
To access the lockout jumper, remove the rear panel per Section 9
and locate jumper “a” in the lower portion of the power supply board
next to the input connectors (see figure at right).
SETTING SOFTWARE LOCKOUTS
When setting up the meter, it may be necessary to
enable specific menu items by setting the corres-
ponding lockout digit to 0. Be sure to reset the lockout
digit to "1" if you do not want the menu item to be
changed by an operator.
Loc 1 Loc 2 Loc 3
Press the MENU key until Loc 1, Loc 2 or Loc 3
is displayed, as desired. Note: the hardware lockout
jumper must be removed (see above).

10. READING COORDINATES OF 2 POINTS SCALING METHOD
When the reading coordinates of 2 points* scaling method has been selected under SEtuP,
the four menu items below will appear ahead of all other menu items when the MENU or
key is first pressed from the run mode.
This scaling method applies a straight line fit between two points, which are determined
from actual transducer signals and the desired corresponding meter readings. A low signal,
such as the output of a pressure transducer at zero pressure, and high signal, such as the
output of the same transducer at a known high pressure, are applied to the meter. The
desired corresponding low and high readings are then entered from the front panel. The
meter then applies straight line fit between the high and low calibration points. This scaling
method has the advantage of calibrating the transducer and meter as a system. The actual
voltage or current at either point does not need to be known. This method is ideal for
process and load cell meters, which require zero and span adjustment. It is also available
for DC or AC meters. It is not available with thermocouple or RTD meters.
The programming example below is for a process meter used with a 4-20 mA pressure
transducer for 0 to 100 psi. Decimal points are set separately using the dEC.Pt menu.

11. DC VOLTS, AMPS, PROCESS, STRAIN
The DC Volts, Amps, Process and Strain meters utilize the DC signal conditioner board, which
needs to be configured via jumpers for the desired voltage or current range. All signal ranges
are factory calibrated with calibration factors stored in EEPROM. The meter software
recognizes the board and will bring up the appropriate menu items for it; however, it does not
recognize the jumper settings. Please see further manual sections for setup of the following:
relay output (15), analog output (16), communication I/O (17), parallel BCD output (18), and
transducer excitation output (19).

2. Use 2.5 mm (0.1") jumpers for locations designated by a lower case letter.
3. Store spare jumpers on an unused jumper post not associated a capital letter.
SCALE & OFFSET SETUP
For DC voltmeters & ammeters, a scale factor of 1 and an offset of 0 are used for direct
readings in (milli)volts or (milli)amperes. Decimal point selection does not affect the displayed
digits. For example, 0-20V or 0-20 mA signals can both be displayed as 0-20000. A full scale
of 20000 may be displayed as 20.000 mA or 20000 µA. Use with a current shunt will require a
scale factor to be set. For example, for a 500-100 (500A, 100 mV) shunt, divide 5000 (the
desired full scale display with 0.1A resolution) by 10000 (displayed value with 100 mV when
the scale factor is 1.0) for a scale factor of 0.5.
For process & strain meters, scaling is normally set up from the front panel using the and
keys, but can also be set up via RS232/485 using special PC-compatible setup software
(available at no charge). The meter allows three scaling methods to be selected: 1) Scale and
offset*, 2) Coordinates of 2 points*, and 3) Reading coordinates of 2 points*. Only menu items
applicable to the selected method will be presented. Please see the Glossary for an
explanation of items marked by an *.

12. LOAD CELL & MICROVOLT INPUTS
The Load Cell and Microvolt meters utilize the load cell signal conditioner board, which offers
sensitivity to ±20 mV full scale and 4 or 6-wire load cell connection. This board needs to be
configured via jumpers for the desired voltage range. All signal ranges are factory calibrated
with calibration factors stored in EEPROM. The meter software recognizes the board and will
bring up the appropriate menu items for it; however, it does not recognize the jumper settings.
Please see further manual sections for setup of the following features: relay output (15),
analog output (16), communication I/O (17), parallel BCD output (18), and transducer
excitation output (19).

Jumpers are 2.5 mm (0.1 in).
SCALE & OFFSET SETUP
For DC microvolt meters, a scale factor of 1 and an offset of 0 are used for direct readings in
microvolts or millivolts. Decimal point selection does not affect the displayed digits. For
example, 20 mV can be displayed as 20.000 mV or 20000 µV. The decimal point is set
separately.
For load cell applications, scaling is normally set up from the front panel using the and
keys, but can also be set up via RS232/485 using special PC-compatible setup software
(available at no charge). The meter allows three scaling methods to be selected: 1). Manual
scale and offset*, 2) Coordinates of 2 points*, and 3) Reading coordinates of 2 points*. Please
see the Glossary for an explanation of each method. Please see the Glossary for an
explanation of each method marked by an *.
