SAFETY INFORMATION Overvoltage / installation categories CAT II: A CAT II-rated meter is suitable for measurements on mono-phase appliances that are connected to the mains by means of a plug and circuits in a normal domestic environment. E.g. household appliances, portable tools… Provided that the circuit is at least 10m apart from a CAT III- or 20m apart from a CAT IV-environment. Pollution degree Pollution degree 2: Only nonconductive pollution occurs.
Features • 40 Mega samples/sec in real time • bandwidth up to 10 MHz • full auto range option • sensitivity down to 0.
QUICK USE OF THE OSCILLOSCOPE After turning ON, a start-up screen appears, also indicating the firmware build version. During this time, some calibrations are performed, so it can take a few seconds before the oscilloscope is ready to use. The scope always starts in full auto set-up mode. This mode can be used for most (repetitive) signals. Set the input coupling to “DC” if very low frequencies or DC voltages are measured (see further). FRONTPANEL 1. signal and menu display 2.
CHANGING THE BATTERIES 4 x AAA Watch the polarity! SHORT MENU Access the short menu by briefly pressing the menu button. The short menu is used to change the most common parameters like volts per division or time- base. For more advanced functions, the extended menu can be used. Enlarge or reduce the signal vertically by adjusting the voltage per division. Adapt the scope readout to the probe setting “x1” or “x10”. Time base: More or less signal cycles will be visible by modifying the time per division.
EXTENDED MENU > Access by keeping the menu button pressed. > Scroll in the menu by using the menu or hold button. > Modify a selection by using the up and down buttons. Select the desired trigger mode (run, normal). Select the triggering at a falling edge of the input signal. or rising Adjust the trigger level. Move the signal vertically over the display (Y scroll bar). Move the signal horizontally over the display (X scroll bar).
USE THE MARKERS AND RECALL THE MEMORY Press the ‘hold’-button briefly. Now two menu screens can be recalled, one is short and the other is extended. Note: If MENU OFF is selected, then the short menu is replaced by quick switching between the markers, V1– V2, t1—t2 1. Press the menu button briefly to call the short menu. OR 2. Keep the menu button pressed to call the extended menu. 3. Press the menu or hold buttons briefly to scroll in the menu. 4.
USING THE COMPONENT TESTER In order to use the component tester, an optional adaptor (HPS141) is required. Full manual coming soon.
