Hi, you just reminded me that I should go for an EKG 😂 Again, one of the things that you don't normally get to, the design - freestanding/built-in is great, beautifully processed. When I get my hands on a device that was made for special purposes, I always think about how it could be modified so that I could use it for something. The last time it was the fire control panel from our building - it will make a beautiful backup or battery source - the basic voltage is +/- 27VDC. Nice day 🙂 Tom
Looking at the construction and components I would date this thing is somewhere in the early to mid 70's. These meters typically have a date stamped on them somewhere.
It is an Bedside Patient monitor early 68-to early 80s, remembers me to this time, a hosptal of 100 beds in the countryside in Germany had 4 of them - no more. Conectors at rear are used to inform a Central nurse desk. Sensivity of ECG input is 1mV, EEG inpunt 0,1 mV. Pulse ist input for an optical fingertip device. This is important feature because a dying Patient with a pacemaker will have ECG actions still - if the patient has cardiac arrest at the same time => pacemaker will trigger the ecg with 72/min and there for no alarm will occur. But thes fingertips with bulb and LDR inside were uncommon.... ita was not a pulsoxymetry at this time, but showed peripher pulse is present = cardiac outout and circulation is present. At that time, TTL technology was not common, so the CRT was a "long" after- glowing type to se a trace glowing. Nice toy for people with an relationship to that time. No use / application for hobby / amateur radio etc.
You mentioned the nice craftmanship of the set esp. the housing - all metric thread, no self drilling screws ! Also a Motherboard / Mainbord was not invented*....all by wire like int the good ol valve-radio set.... * of course hp had it at that time-LOL. But the SIMENS chassis was a quality of its own.... hp had selfdrilling ugly screws....
thanks a lot this is very useful information, however i am not able to look this up, EU official standard for 230V is dated 2008 when i try to double check this.

Nice! I was waiting for you to pull the one knob and check out the signal trigger.

This could be a nice panoramic/spectrum display perhaps, especially for slower sweeps.

you are right 🙂
Der står 220V på bagsiden. Det fortæller at det er før 1988.
