Timebase 10uS/div - 500uS/div in "1-2-5" steps
Capture buffer size 1024 bytes
Trigger modes Automatic/Normal/Single
Display size 2.4" (61mm)
Display resolution 320 pixels x 240 pixels
Input impedance 1M ohm/20pF
ADC resolution 12-bits

The DataLogger section at the top of the screen displays:-

Vpp - Shows the difference between the exteme Maximum and Minimum values
Vavr - The Average reading is the mean vertical level of the entrie captured waveform
Freq - The Frequency is the inverse of the Period and is measured in Hertz

Pressing the [SELECT] button steps the user through the various control settings displayed around the edge of the screen, the currently active setting being highlighted within a blue frame. AT each setting, pressing the [-] and [+] buttons will step through the available options.

Pressing the [HOLD/OK] button will freeze the current display allowing for closer inspection of the input signal.

Pressing the [HOLD/OK] button while in the lower left corner of the screen, the user can toggle the [AUTO SIZE] ([A.S]) function on and off. When enabled, [A.S] will automatically resize the input signal to fill the scope display area. This is useful when you have a signal on the display which doesn't optimally fit in any of the [VOLTS/DIV] settings. The DataLogger still displays the correct data for the input signal.
