Measuring Value Display And History Memory - Bender ISOMETER isoRW425 Manual

5.7 Measuring value display and history memory

In R mode only R
(standard display). All other measuring value displays switch to the standard
display after a maximum of 5 minutes. The fault location will only be stored in
the history memory (HiS) in R mode. In Z mode only will Z
tory memory. The pulse symbol indicates a current measured value. If this
symbol does not appear, the measurement is still running and the latest valid
measured value will be displayed. The symbols < or > will be displayed addi-
tionally to the measured value when a response value has been reached or vi-
olated, or the measured value is below or above the measuring range.
