*22 The form of display depends on value range as shown in the tables below:
VT primary setting value determines the minimum number of digits to be displayed on each measurement display.
When a value to be displayed exceeds the max. value of the display range, the max. value will blink.

*23 When a communication card is connected, waveform data in the event of system fault can be read.
(See the section 4 “Function”).
*24 When the product is shipped from the factory, each setting value is “Lock” (With lock setting element) or “minimum
setting value“ (Without lock setting element).
