3.7 Making Measurements in BPD TEST
Mode
To determine open fault and deterioration of bypass diodes
connected to a solar panel, measure the bypass diode and bypass
route resistance.
WARNING
Observe the following to prevent an electric shock,
short-circuit, or damage to the instrument.
• Do not measure under a live circuit condition.
Doing so could damage the instrument or cause an
accident that might result in injury or death. Always
turn off power to the measurement object before
starting.
• When measuring a bypass diode, dangerous
voltage is applied to the measurement terminals.
To prevent an electric shock, do not touch the test
leads.
• Press the MEASURE key fully down until a live circuit indicator lights up.
If the button is not pressed down fully, a proper measurement cannot be
made.
• After use, set the rotary switch in OFF.
