- D
  Deborah BlakeAug 4, 2025
  There are several reasons why the NF Inverter's output value might be abnormal: 1. The equipment may not have warmed up sufficiently. Allow it to warm up for at least 2 hours after powering it on. 2. The ambient temperature and humidity may be outside the performance guarantee range. Ensure the equipment is used within specified environmental conditions. 3. A DC offset might be applied. Set the DC offset to 0 V. 4. The unit might be set to Vrms instead of Vp-p. Set the unit to Vp-p. 5. The load option might be set to /50. Set the load option to /OPEN.
