4) OPERATION ACV & DCV functions Set the slide-switch function-selector to the position. Default at last selected function. Press SELECT button to toggle between ACV and DCV measurement functions. There is no LCD annunciator for DC. LCD annunciator “ ” turns on to indicate AC is selected. Line-level Frequency function When voltage or current function is selected, press Hz button momentarily toggles to Line-level Frequency function. - Page 6 When voltage or current function is selected, press and hold THD%-R button for one second or more toggles to Total Harmonic Distortion - RMS measurement function. The LCD annunciator “%” turns on. Note: Specified accuracy at ACA fundamental > 5A; ACV fundamental > 50V. The meter displays “---.- %”...
- Page 7 Temperature function Set the slide-switch function-selector to the F position. Default at last selected function. Press SELECT button to toggle between C and F measurement functions. Be sure to insert the banana plug type-K temperature bead probe Bkp60 at correct polarities.
- Page 8 Press and hold the “Hi-Lo Log” button for one second or more to start “ ” a new Hi-Lo Logging session. All previously logged data is erased! Annunciators “Max Min” flashes and real-time measurement readings are being displayed. Press SELECT button momentarily toggles to display logged data item number (number of one-minute time intervals).
- Page 9 To recall, switch on the meter, then press the forward “ ” and backward “ ” arrow buttons at the same time to recall “ ” the logged data. The meter displays in turn the absolute maximum item number, absolute maximum reading, absolute minimum item number, and then absolute minimum reading (of the whole logging period).
