Accu-Gold Touch User Guide
Introduction
The Accu-Gold Touch is the next generation X-ray measurement system at the heart of which is a compact multifunction
digitizer module and powerful, intuitive firmware. Accu-Gold Touch with its built-in display is a compact, cost effective, and
multi-function X-ray analyzer and uses the latest technology in solid state sensors, gold standard ion chambers, mA, and
light sensors.
Accu-Gold Touch has features to increase
your productivity such as: quick setup,
ease of use, automatic settings and
multiple-parameter data capture, unique
remote operation, easy data analysis, and
instant data recall. With an Auxiliary sensor
input and customizable software, you have
the capability to expand to meet future
needs. The Accu-Gold Touch provides the
ability to save all of your measurements.
The Accu-Gold Touch system consists of a
built-in digitizer module whose function is
to transform the analog signals generated
by a host of sensors into calibrated digital
signals. The Touch is available in different
models that are suited for specific
applications, the differences being which
sensors can be used.

Settings –
Measure –
Trigger Sensor: Chosen automatically. If more than one
sensor is plugged in, it will trigger off of the multisensor.
If no multisensor, then the dose diode. If neither, then the
ion chamber. The sensor used for triggering will be
indicated on the Exposure Info panel for that
measurement (see pg 5).
Trigger Mode: Manual trigger disables the trigger and lets
you start and stop a measurement by pressing a button.
Trigger Level: “Std” trigger sensitivity is recommended.
Select “Low” if “Std” is not low enough. “Low” may allow
smaller signals to be captured, but may also result in false
triggers. Select “High” if “Std” causes false triggering.
Dental Mode: Designed to accommodate the initial
pre-heat kV pulses commonly found with some dental
generators. The dose remains integrated over the entire
exposure and only the kV and time calculations are affected.
End Delay: Many modern x-ray generators now feature scout exposures which may introduce gaps of several seconds
or more in the radiation output. In some instances, if the end of exposure delay is not long enough Accu-Gold may
attempt to display the exposure results while the generator is finishing the exposure. If this situation is encountered,
you may select an end of exposure delay of up to 8 seconds. The dose remains integrated over the entire
exposure and only the kV and time calculations are affected. The scout pulse will be ignored in the Dose
Rate calculation. 7

Anode/Filter –
The anode filter calibrations that are available
for making measurements will depend on the
multisensor you use. A diagnostic
multisensor will only show the diagnostic
calibrations, an ion chamber will show none.
Some calibrations require that the
multisensor have a particular built in
calibration and will only show up if that is the
case. Chose the calibration appropriate for
the machine you are measuring.

Measurements may be exported to
a USB flash drive and can be
viewed using Accu-Gold 2 software
(V2.46 or later). Copy the exported
file to a PC with AG2 on it.
Double-click this file and it will open
in the AG2 software.
The Touch only shows the last
300 measurements but will export
all of its measurements breaking
up the files into sessions.
(A session is all the measurements
between the time the Touch is
turned on and then turned off.)

Measurement Results Customization –
The Measurement Results on the customizable pages, C1 and C2, can
be customized to show any output on either page. Multiple sensors can
be combined on a single page showing the results of interest without
having to change pages.
Touch any measurement result. A page opens up that lets you replace
the result shown with another. Choose the one you want and then press
Back.
Color coding indicates the source of the

Setting up the Hardware
1. Connect the sensor(s) to the Touch.
2. Position the sensor to make a measurement.
Note: Position the sensor before pressing the Play button; moving the sensor or cable while it is measuring
may trigger a false measurement.
3. Place the sensor in the path of the X-ray beam.
Note: Make sure the temperature of the ion chamber (if used) has stabilized before making a measurement.
4. Press the Play button.
5. The firmware begins to initialize the hardware as indicated by the status at the bottom of the screen. If an
ion chamber is connected, the bias supply needs to start and stabilize.
6. As soon as the “READY” message is displayed at the bottom of the screen, you can make a
measurement.
7. Activate the X-ray machine to capture the exposure data.
8. The Touch automatically saves and displays the data for the measurement when the exposure is complete.
9. At any time you can review outputs of the current measurement or previous measurements. Make additional exposures as necessary.
Note: All measurements are automatic (except for Manual Trigger Mode) until you press the Pause button.
10. If you need to reposition the sensor(s), click the Pause button to temporarily take the sensor offline and prevent any inadvertent null
exposures from being added to your measurements.
11. Click the Play button when you are ready to make your next measurement.
Measurements Using Solid State Mammographic Sensors
Before making an exposure, make sure to choose the Anode/Filter combination that best represents the machine being measured (see
page 8 & 9). Radcal sensor calibrations assume a 2.2 mm polycarbonate paddle, or simulated paddle (Model 8154), is placed on top of
the sensor.
Making a Measurement with multiple sensors connected
The Accu-Gold Touch allows you to connect up to five sensors (depending on model) simultaneously and collect data from all of the
connected sensors.

Battery Charger
The battery icon on the display indicates an approximate state of charge. When the battery level drops to approximately
to 25%, the LED will start to blink green/red (or blue/red in WiFi mode).
The charger that is supplied with the Touch has been chosen to optimize the charging of the battery. Typical charging time
for a fully drained battery is approximately 5 hours.
The LED shows yellow (magenta in WiFi mode) when the charger is plugged in. Blinking means that it is charging, solid
when complete. The Touch can be used while being charged and the charger may be left connected indefinitely.
If the battery has been exhausted, there will be a small delay while it charges up enough to operate.
The Touch can be charged using other chargers or even using the USB port of a computer but the
charging time may vary depending on the source and how it is recognized.
USB Flash Drive
Firmware updates will be provided from time to time. In order to install an update, using the link provided, download the
files onto the flash drive. Additional instructions will be provided at that time.
CAUTION
Do not dispose of product in heat, fire or water. Misuse, dropping, or excessive force may cause product damage.

USB Mode - Using Accu-Gold 2 software
Connect the control unit to a PC using the supplied micro USB cable (or use a standard USB-A to USB-B micro cable)
and attach any sensor that you would like to measure with. The maximum USB cable length is 3 meters. You can use
a 5 meter cable but you may experience interference issues in some cases. Over 5 meters requires using an active
extension (contact Radcal).
Launch Accu-Gold 2 on you computer and select "Connect via USB" on the Start screen.
Refer to the Accu-Gold 2 User Manual when in USB or WiFi Modes.
When the software displays the "Ready" status in the lower left corner of the window you can begin measuring.

Accu-Gold Touch User Guide
WiFi Mode - Using Accu-Gold 2 software
Power on the control unit and select "Wifi Mode" on the start screen then click "Start Wi-Fi"
The Display on the control unit will go blank, when the Blue LED blinks rapidly it is ready to connect. Launch Accu-Gold 2
and select "Connect via Wi-Fi" on the start screen. When the software displays "Ready" you can begin to measure.
If the connection fails, go to the windows connection manager
and select TouchXX-XXXX and click connect.
If a PIN is requested click the underlined text below "Connect
using a security key" and enter 12345678 for the password.
Once connected the status will be "No Internet, Secured".
You can now click the "Start" button on the measurement
screen and standby for initialization.
When finished, turn off the unit. There might be a delay before
the LED goes out.
