2 Manual Testing
2.1 General
The vPad-Mini app, in its most basic mode, is a manual electrical safety tester. Test results are only saved if
you manually record the measurement value. There is no evaluation of passing or failing against any limit
values you wish to impose. After applying power to the smart phone, the main menu of the application is
shown (Figure 1). Note that the main menu appearance will change as the recording and the automation
options are enabled: the number of buttons will change from 2 to 3 to 4 respectively.
The UI of the main menu includes image buttons which launch other activities of the app, including
measurement activities such as voltage , equipment current , ground resistance and leakage
, as well as application and device settings . Context-sensitive help is accessed on this and other
screens by a button.

2.2 Settings
The button on the main menu of the app launches a Settings Menu (Figure 3).
A spinner control sets the electrical safety standard (Figure 4). This setting affects the types of tests
provided by measurement activities of the app, as well as nomenclature which is displayed by those
activities.
Figure 4
Standards supported by vPad-Mini are AAMI-ES1, NFPA 99, IEC 60601, IEC 62353, IEC 61010, VDE751
and AU/NZ 3551. On first run of the app, the default standard will be AAMI-ES1. The selected standard
appears on most menus of the app, including the main menu where it is shown above the button.

Figure 6
A second spinner control sets the polarity switching delay (Figure 5). This setting applies to the leakage test
activity and determines the amount of time the test receptacle is maintained in the OFF state between
changes in polarity from normal to reverse or vice versa.
Available settings are 2, 4, 6 or 8 seconds. On first run of the app, the default setting is 2 seconds.
In Figure 3, there is a Main Menu AC Power setting. The user has the option of leaving the AC Power ON
(per Figure 3) whenever you go back to the Main Menu from a measurement that had the receptacle ON, or
having the AC Power turned OFF whenever you return to the Main Menu ( Always OFF).
The button displays the Android Settings of the phone (Figure 6). Except for language and perhaps
the sound volume, users will normally have no need to change the settings of the phone itself. However,
access to the Apps submenu of the Android Settings will be necessary if the vPad-Mini app needs to be
updated in the field with a new version, or you wish to use QuickSupport (from Teamviewer) for remote
support. The Android Settings menu will also enable the vPad-Mini phone to be paired with the customer's
phone or tablet over Bluetooth, which will be necessary if data recording, automation and reporting
capabilities are activated in the future.

The phone's BACK button is used to exit the Android Settings menu.
The button of Figure 3 saves changes, if any, to the safety standard, polarity delay and/or receptacle
status on returning to the Main Menu, and closes the Settings Menu.
2.3 Voltage
The button of the main menu launches a voltage measurement (Figure 7).
A numeric readout occupies the entire upper half of the screen. The measured value is updated
approximately once per second.
Image buttons occupying the bottom half of the screen enable the user to control the safety analyzer.
The button finishes the measurement and returns the UI to the main menu. The phone's BACK
button is disabled.
The button displays help information relevant to this menu.

Figure 8
The large central button selects the type of measurement to be performed.
2.3.1 The button displays a schematic image which represents the measurement being displayed
on the upper half of the screen.
2.3.2 Initially the button image is set to L1-L2 voltage.
2.3.3 When the central button is pressed, a pop-up pick list is then shown which allows the user to
change the type of measurement, Figure 8.
As shown in Figure 8, this list provides four measurements: L1-L2; L1-GND; L2-GND and
point-to-point voltage. The nomenclature of the pick list depends on the standard which has
been selected via the Settings Menu of Section 2 (AAMI and NFPA standards measure
"line" voltages; IEC standards measure "mains" voltages).
2.3.4 When an item on the pick list is chosen, the list is dismissed and the schematic on the central
button is updated to reflect the new test, and the selection label is copied to the text field
above the schematic.
The toggle button at bottom right controls the test receptacle.
The button icon includes a representation of a LED indicator, which appears bright green when the
receptacle is ON or grey when the receptacle is OFF.

2.4 Load Current Activity
The button on the main menu measures and displays load current. This measurement is somewhat
simpler than others on the app since it provides only one type of measurement.
A numeric readout occupies the entire upper half of the screen. The measurement value is updated
approximately once per second.
The button finishes the measurement and returns to the main menu. The phone's BACK button
is disabled.
The button displays help information relevant to this menu.
A schematic diagram is shown between and buttons which represents the test configuration. This
is an image only, not a button. A description of the test is placed in a text field above the schematic.
On entering the menu, the test receptacle is automatically switched ON if it is not already ON. Exiting this
activity with the button does not change the state of the test receptacle, so it will remain ON while
the main menu is being viewed.

2.5 Resistance
The button on the main menu starts a resistance measurement (Figure 10). The UI of this activity is
similar in design to the UI for the voltage measurement (see Section 3).
A numeric readout occupies the entire upper half of the screen. The measurement value is updated
approximately once per second.
All measurement results are obtained with a dedicated ohmmeter circuit which measures over a single range
up to ~2 ohms.
Image buttons occupying the bottom half of the screen enable the user to control the safety analyzer.
The button finishes the measurement and returns the UI to the main menu. The phone's BACK
button is disabled.
The button displays help information relevant to this menu..
The large central button selects the type of measurement to be performed.
2.5.1 The button displays a schematic image which represents the measurement being displayed
on the upper half of the screen.
2.5.2 On initial entry to the resistance measurement, the button image is set to power cord or
protective earth resistance. This means that, in addition to enabling the ohmmeter circuitry,
the test receptacle will be switched OFF if it is currently ON.
Installation/Chapter 2 #Page 10

vPad-Mini OPERATORS MANUAL
Figure 11
2.5.3 When the central button is pressed a pop-up pick list is then shown which allows the user to
change the type of measurement.
As shown in Figure 11, this activity provides two measurements: power cord or PE
resistance and point-to-point resistance. The nomenclature of the pick list depends on the
standard which has been selected via the Settings Menu described in Section 2.2 (AAMI and
NFPA standards measure "power cord" resistance; IEC standards measure "protective
earth" resistance).
2.5.4 When a item on the pick list is chosen, the list is dismissed and the schematic on the central
button is updated to reflect the new test, and the label for the selection is copied to the text
field above the schematic.
The toggle button at bottom right controls the test receptacle. Note that it will be OFF when
testing the power cord, and may be OFF or ON when testing point-to-point resistance.
The button icon includes a representation of a LED indicator, which appears bright green when the
receptacle is ON or grey when the receptacle is OFF.

2.6 Leakage Currents
The button on the main menu initiates leakage current measurements (Figure 12). The UI of this
activity is highly dependant on the setting of the standard, and in this way the leakage measurements differs
somewhat from other parameters.
A numeric readout occupies the upper right corner of the screen. The measurement value is updated
approximately once per second.
The metering circuitry provides two filter settings. The AAMI filter is selected when the standard is set to
AAMI only. For all other standards, the IEC filter is used.
When the standard is set to IEC61010 and the selected test is "Accessible Voltage", an alternative
measurement process is used which is analogous to the point-to-point measurement of the voltage activity.
Image buttons on the bottom half of the screen enable the user to control the leakage test.
On initial entry to leakage current testing the button icons default to show normal polarity and (depending
on the standard) normal neutral and ground.
The button displays help information relevant to this menu.
The "ground button" controls the ground or earth connection at the test receptacle.
