selected & the meter will go into manual ranging mode.
3. Press the PEAK button, Pmax will display.
4. The display will update each time a higher positive peak occurs.
5. Press the PEAK button again, Pmin will display. The display will
now update and indicate the lowest negative peak.

until the Pmin or Pmax indicator switches off.
NOTE: If the Function switch position is changed after a
calibration the Peak Hold calibration must be repeated for the
new function selected.
