2. LOG Input Specifications

2.1. Converting the LOG Input (Relationship between the Input Voltage and Digital

Display)

Trend display (logarithmic scale): Displays the input voltage on a logarithmic

scale.

Digital display: Displays the result obtained by converting the

input voltage using the equation below.

¾ The relationship between the input voltage of special LOG range and digital

display value is shown below.

Input voltage X

Lower limit of display span VL Upper limit of display span VU
