Heart Rate Coupler (model 567)
for triggering by signals from the ECG Coupler (or Pressure Coupler when the pressure wave has a fast enough rise/fall time).
2 ranges: 20-200 bpm up to a maximum of 600 40-400 bpm
up to a maximum of 1200.
Threshold sensitivity: 3 ranges and continuous adjustment; 10 / 100 / 1000
Input voltage: 5 mV ... 10 V
Input resistance: 100 kOhm
Adjustable polarity +/-
Zero suppression to expand a small heart rate range to fullscale by shifting
zero up to 150% of selected range for easy creating your own rate scale
on the chart paper.
Calibration: 15 steps, 0-150% of selected rate range.
The Heart-rate Coupler can be connected to a contact electrode and used
as a drop counter.
