Input selector
Connect to the LOGIC receptacle
Clips
1 Set the input selector in accordance with
the measured voltage.
LOW range: On/off for 100 VAC and 24
VDC, etc.
HIGH range: On/off for 200 VAC, etc.
2 Connect the clips to the measurement
object.
• Inputs are non-polarized, so polarity can be disregarded.
• Inputs are isolated, so each channel can be connected to a point of indepen-
dent potential.
• This instrument detects absolute values, so DC of either polarity can be input.
• AC voltage is evaluated as a 50/60 Hz standard sine wave.
