info@tursdaletechnicalservices.co.uk Making Measurement Introduction Chapter 3 explains how to make measurements. You could turn the Meter off by turning to OFF position or set up the sleep mode from 1-30 minutes. Please must ensure the Meter is not under sleep mode if you turn the Meter on but without display. To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator “... - Page 9 info@tursdaletechnicalservices.co.uk ACV, DCV, Hz, ACA and DCA range Turn the rotary switch to ACV, DCV, Hz, ACA or DCA range, the Meter displays digital reading (Multimeter mode). Press Mode to switch to waveform display (scope mode) as below Figure 4. When entering scope mode, time base is auto trace, the amplitude is manual set, you may need to re-set them.
