Chroma 61705 - Phase Angle Calibration

Programmable AC Source 61705 User’s Manual
4-6
1. The resistance of applied load must be constant, so that the load
current is proportional to output voltage. If not, the step B of
CURRENT MEAS. ACCURACY will be insignificant. Users only
need to meet the current of step C when output voltage is 125VAC.
2. When performing the calibration, the protection is removed
temporarily. It may cause damage to AC Source if applying unsuitable
load.
4.2.3 Phase Angle Calibration
In order to get better accuracy of phase angle among each output voltage, especially at high
frequency, 61700 Series AC Sources allow users to calibrate it. Select 4 to go to phase
offset calibration at PHASE CHOICE PAGE (see 4.2).
Confirm no load is connected and then press ENTER to select phase offset calibration.
