Page 7: Starting Up The Multimeter
2.2 Starting up the multimeter The switch is in the OFF position. Turn the switch to the function of your choice. All the display segments appear for a few seconds, then the screen for the selected function is displayed. The multimeter is now ready for measurements. Le commutateur est sur une autre position : appuyez sur la touche 2.3 Turning off the multimeter The multimeter can be turned off either manually by returning the switch to the OFF position, or automatically after ten... - Page 8 In V , the measurement signal goes through the low pass filter with a cut-off frequency of < 300 Hz. When LowZ measuring a voltage with a frequency in excess of 150 Hz, it is considerably reduced and therefore a significant error can occur.

Page 10: Key Functions
3.2 Key functions The functions can be accessed by pressing a key repeatedly, using short or long presses. Every push on a key is validated by a sound signal. 3.2.1 When the quantity V or A is selected, the multimeter is in AUTO AC/DC. It then determines whether the measurement is an AC or DC measurement. -
