
Enable Trace Separation
Select FHR waveform, in the pop-up [FHR SETUP] menu, select [FHR OFFSET] and select [+20bpm]
or [-20bpm]. [+20bpm] or [-20bpm] means the FHR2 trace is displayed and recorded 20bpm higher or
lower than it really is respectively. The FHR2 trace recorded on the recording paper is thinner with light
color.
Take +20bpm offset as an example, see the figure below:
Figure 14-3 Trace separationenabled
The FHR2 trace on the recording paper has an offset, but the FHR2 value on the screen remains
unchanged. Subtract 20 from the recorded trace for FHR2 to obtain the true FHR2. For example, if the
recorded FHR2 trace is 180bpm, the true FHR2 is 160bpm.

Disable Trace Separation
Select FHR waveform, in the pop-up [FHR SETUP] menu, select [FHR OFFSET] and select [+0bpm].
