% Line Voltage THD Menu
• Menu Heading - “LT-”
• Measurement at Menu Heading - % Line Voltage THD
• Submenu - yes
“HI=” - Highest % THD
“Lo=” - Lowest % THD
“A=” - Average % THD
“LC=” - Crest factor of the line voltage
The submenu values are the highest, lowest, and average values taken since
the SureTest was plugged in.
