Introduction
The Vertu digital panel meter is one of the most
versatile digital panel meters on the market and will
satisfy a wide variety of process and temperature
applications. The Vertu can be field programmed to
accept process voltage (0-5V, 1-5V, etc) and current
(4-20 mA) inputs, 100 Ohm RTDs, and the four most
common thermocouples types.
One of the Vertu’s most useful features is its ability
to provide 24 VDC to power the transmitter’s 4-20 mA
signal. This reduces costs and simplifies wiring. The
Vertu is housed in a shallow-depth, 1/8 DIN enclosure
that features a NEMA 4X front panel and convenient
mounting hardware. There are two power options for
the Vertu: 85 to 265 VAC or 12-36 VDC and certain
configurations of the AC powered meter can provide 24
VDC to power the transmitter, if needed. Programming
and setup can be performed with the four front panel
pushbuttons, free DisplayWizard software or using the
Copy function.
Two relays and isolated 4-20 mA output options
increase the utility of the Vertu meter. The relays can
be used for alarm or control applications. The 4-20 mA
output provides an isolated retransmission of the input
signal; especially useful for temperature inputs like
thermocouples and RTDs.
The display height on the Vertu VPM3000 is an
astounding 1.2" (30.5 mm) and can be read easily from
distances of up to 30 feet!
The intensity of the display on the Vertu can be
adjusted to compensate for various lighting conditions,
especially direct sunlight.

connector.
Figure 22. Relay & 24 V Output Connections
Switching Inductive Loads
The use of snubbers to suppress electrical noise is
strongly recommended when switching inductive loads
to prevent disrupting the microprocessor’s operation.
The snubbers also prolong the life of the relay contacts.
Suppression can be obtained with resistor-capacitor
(RC) networks assembled by the user or purchased as
complete assemblies. Refer to the following circuits for
RC network assembly and installation:
Figure 23. AC and DC Loads Protection
Choose R and C as follows:
R: 0.5 to 1 Ωfor each volt across the contacts
C: 0.5 to 1 µF for each amp through closed contacts
Notes:
1. Inductive relay rating is 1/14 HP (50 W) at
115/230 VAC
2. Use capacitors rated for 250 VAC.
3. RC networks may affect load release time of
solenoid loads. Check to confirm proper
operation.
4. Install the RC network at the meter's relay screw
terminals. An RC network may also be installed
across the load. Experiment for best results.

standards, so for initial setup, it is recommended to
use the (ScAL) function.
The Program menu contains the Scale (ScAL) and the
Calibrate (Cal) menus.
Process inputs may be scaled or calibrated to any
display within the range of the meter.
Scaling the Meter (scal)
The process inputs (4-20 mA and ±10 VDC) can be
scaled to display the process in engineering units.
A signal source is not needed to scale the meter;
simply program the inputs and corresponding display
values.
For instructions on how to program numeric
values see Setting Numeric Values, page 19.
Note: The Scale menu is not available for
temperature inputs.
Error Message (Err)
An error message indicates that the calibration or
scaling process was not successful.
After the error message is displayed, the meter
reverts to input 1, allowing the appropriate input
signals to be applied.
The error message might be caused by any of the
following conditions:
1. Input signal is not connected to the proper
terminals or it is connected backwards.
2. Wrong signal selection in Setup menu.
3. Minimum input span requirements not
maintained.
4. Input 1 signal inadvertently applied to calibrate
input 2.
