  • Page 17 OPERATORS MANUAL 2.4 Load Current Activity 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. Figure 9 A numeric readout occupies the entire upper half of the screen. The measurement value is updated approximately once per second.
  • Page 18 OPERATORS MANUAL 2.5 Resistance 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). Figure 10 A numeric readout occupies the entire upper half of the screen. The measurement value is updated approximately once per second.
  • Page 19 OPERATORS MANUAL 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. Figure 11 As shown in Figure 11, this activity provides two measurements: power cord or PE resistance and point-to-point resistance.
  • Page 20 OPERATORS MANUAL 2.6 Leakage Currents 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.
  • Page 21 OPERATORS MANUAL The "ground button" may be disabled or hidden depending on the selected leakage test. For AAMI and IEC60601 earth leakage, the button is disabled, its image is set to the open-circuit icon, and the ground at the test receptacle is maintained in the open state. For IEC62353 equipment leakage, and for AAMI isolation or IEC MAP tests, the "ground button"...
  • Page 22 OPERATORS MANUAL The "polarity button" is enabled for all leakage tests unless the standard is set to NFPA, in which case the button is disabled and all measurements are performed with receptacle polarity set to normal. When the selected leakage test is the AAMI (lead) isolation test, the IEC60601 MAP test, or the IEC62353 applied part leakage test, the ground and neutral buttons on the UI are hidden and a button which controls the MAP test voltage is then shown (see Figure 14).
  • Page 23 OPERATORS MANUAL An image button located at the top left corner of the UI enables the user to select the leakage test type. Figure 16 The content of the pick list depends on the standard which has been selected via the Settings Menu of Section 2.2, as follows:...
