INSTALL TOOLBOX
ToolBox offers a smart, no-fuss setup experience for your GF40 universal indicator.
It features USB powered programming (no power supply required!) and has been
designed to simplify and speed up configuration.
You must install ToolBox before connecting the GF40 to your computer. If you
have already connected the meter using the USB Bridge Key, please disconnect it
before continuing.
A
Download the latest version of ToolBox from
www.defineinstruments.com/toolbox
For ease of access, we recommend saving the install file on your desktop. If you cannot locate
the install file, check whether your browser has saved it in your Downloads folder.

B
Extract the install file from the zip folder. Right-click on the zip folder and choose
'Extract All', (or extract the file using another extraction utility of your choice).
C
Double-click on the extracted .msi
install file. This will launch the
ToolBox installer.
Depending on your security settings, a 'Security Warning' dialog
may appear.
If you see the security message, click
'Run'.
D
The ToolBox setup wizard
will launch. Click 'Next'.

E
The
wizard
will
ask
for confirmation that
you wish to begin the
installation.
Click 'Next' to continue.
F
The wizard will prompt
you to select an installation folder.
You may accept the default installation folder, or
select an alternative location by clicking 'Browse'.
Click 'Next' to continue.
G
Wait while the install wizard installs ToolBox.
H
When the installation has
successfully completed,
the following dialog will
appear.
Click 'Close' to exit.
The downloaded zip and
.msi installer files are no
longer needed, and may
be deleted if desired.

CONNECT USB BRIDGE KEY
BEFORE YOU CONNECT:
1
Install the ToolBox software (see Section 3) before connecting the USB
Bridge Key to your computer. ToolBox may not be able to detect an indicator that was already connected to your computer at the time of installation.
2
Ensure that all cables and adaptors are securely connected to both the
USB programming key and your indicator. Connecting your indicator with
cables that are not firmly 'pushed in' could cause damage to your computer.
Connect the GF40 to your computer's USB port using the USB Bridge Key. The interface cable connects to the USB programming jack on the unit's back panel (see
2.2D).

SOFTWARE CONFIGURATION USING TOOLBOX
The ToolBox software enables full configuration of your GF40 universal indicator.
To set up your indicator, only the USB connection is required - you do not need to
supply power.
ToolBox features a comprehensive help panel that will guide you through the setup
of your GF40 universal indicator. Helpful hints and explanations will appear when
you adjust a setting using the ToolBox controls.
There are three main navigation pages/tabs:
›
Input/Output: Input mode/range, Scaling/offset, Display settings, Retransmis-
›
sion scaling
Setpoints: Alarm control/mode, Setpoint activation points, advanced modes
›
Advanced: Load/save configuration, Create configuration certificate
5.1 - Connect to your GF40 using ToolBox
A
Double-click the ToolBox icon on your desktop to launch the ToolBox program.
B
With the GF40 connected to your computer's USB port (see Section 4), click the
'Connect' button. This will scan your computer's Com ports and automatically
connect to your device.
If ToolBox cannot detect or connect to your device, try disconnecting and reconnecting the
meter, and then click 'Connect' again.

WIRING
6.1 - Wire the universal input
See 2.2A, pins 1–6
The input terminal can be wired to suit numerous input types. See Section 7 for input
wiring, or refer to the ToolBox help panel as you are configuring the unit.
6.2 - Wire the analog output (If installed)
See 2.2C, pins 9–10
If your model includes analog output, wire it as shown (right).
The analog output can be scaled to suit your application using the
ToolBox software.
6.3 - Wire the relay outputs
(If installed) See 2.2F, pins 13–16
If your model includes relay outputs, wire them
as shown (right). The relay reset switch is optional
and can be used if desired.
The setpoints can be configured using ToolBox for
a variety of alarm or control functions.
6.4 - Wire the power supply
See 2.2B, pins 7–8
Wire the unit for low or high voltage, depending on
your model's power supply. Never connect a low
voltage unit to mains power.
Once you have completed the wiring process it is safe
to switch on your power supply.

Temperature (RTD)
The RTD (standing for Resistance

accurate, and is fast becoming the most
popular temperature sensor in industry.
Often referred to as PT100 and PT1000,
the PT represents platinum (the dominant metal in its construction), and 100/
1000 is the resistance in ohms at 0°C.

7.3 - NTC input
NTC -55 to 125°C (various thermistors)
Sensor types 10K Beta 3984/3435
Temperature (NTC)
NTC (Negative Temperature Coefficient),
is a particular type of thermistor.
NTC's are popular in the HVAC industry
due to their low cost, but have a limited
temperature range which makes them
less popular in general industry.
The biggest issue with their general
acceptance is that there is no standard
that covers interoperability between different thermistor manufacturers.

7.4 - Current input
Range 0/4–20.000mA
Max over-range 50mA DC continuous
USB prog zero 0–±99% of span
Linearity and repeatability
<±0.02% FSO typical
Field prog span 1μA–24mA DC
Input resistance 10Ω
0/4–20mA DC
0/4–20mA DC is the most commonly
used analog signal in industry, and is universally accepted. As a current loop, it is
unaffected by voltage drops in cables,
and can be transmitted over long distances without signal degradation.
0/4–20mA DC, 3 or 4 wire
transmitter
The meter can provide up to 50mA to
power an external 3 or 4 wire transmitter, and at the same time measure the
signal.
4–20mA DC, loop powered
transmitter
The meter can provide power to a loop
powered transmitter, and at the same
time measure the signal. This configuration is ideal for when there is a long distance between the sensor and the meter.

A -200mV to 1V range is provided for
interfacing to sensors and other electronic apparatus that provide this output.
±10V DC is a common process signal

General Frequency mode allows an NPN
or PNP input (up to 2KHz) to be measured and scaled to any engineering unit.
The meter can also provide up to 50mA
to power an external device.
Flow rate mode
Flow Rate mode enables an input from
an NPN or PNP paddle type flow meter
to be converted to a flow rate. The
input signal (up to 2KHz) is converted
into a flow rate by programming the
unit with the sensor manufacturer's
K-factor value.
to power a 3 wire NPN paddle type flow
sensor.
RPM mode
PNP open collector output
ToolBox RPM mode enables an input
from an NPN or PNP proximity sensor
to be converted to an RPM (Revs Per
Minute) value. The input signal (up to
2KHz) is converted into RPM by programming the unit with the pulses per
revolution value.
