4.2 Displaying the Deviation from the Reference Value
4-5 ZM2371/ZM2372
The displaying ranges for deviation% both for primary and secondary parameters are shown
as follows:
Deviation% ±(0.000 to 999.999), Fixed decimal place
The unit of reference value depends on the parameter. (ex.: Z → Ω, θ → )
When the parameter is changed, the unit to be displayed is also changed.
(ex.: C, 2.2mF → L, 2.2mH)
When the primary or secondary parameter to be displayed is changed, the display is
changed from the one of deviation and deviation% into the other of original measured value
as is for both primary and secondary parameters. To display the deviation or deviation%,
previously set the given primary and secondary parameters. Also confirm that “Δ” is
displayed in front of measured value.
The display format for measured value and the comparison format for comparator are
common. Also the reference value for obtaining the deviation is common for both display and
comparator. For both primary and secondary parameters, even if either display or
comparator is set up, the same display format or comparison format or reference value is
obtained.
