Description: exact item shown. works well. I don't have a D-cell (can you believe that - after all the flashlights we used them in, I now don't even have one in the house) so I powered off my test bench power supply set to 1.5V. it works correctly, calibrates when you put the switch to standard and then set to zero, and it reads the temperature accurately with a thermocouple connected (see video, presuming ebay approves it). this is a very cool older design with a standard cell (that's the glass item in the penultimate photo, and a bridge circuit. It has high precision resistors and no solid state components, no active circuitry, just a precision bridge and a galvenometer. you balance the thermo couple, and the standard cell with the battery making up the difference, and the balance setting (the horizontal knob) turns a tape that displays a value that you read for the temperature. I wrote the company to see if I could get a manual for it and all they could find was a manual for the Micromite (a later unit) which is dated 1984, this unit must be at least 10 years older, it might date back to the 1960s. and just think, it's working perfectly - it was there near the 60s and survived...... (ok so much for humor)... The video shows me finding the right range and balancing out the voltage from the thermocouple (that's when I adjust the meter to 0), and then I put my finger on the thermocouple and you can see the meter respond, it moves too low, telling you that the setting is now to low and you need to raise the cancelling voltage (represented by the temperature values on the readout tape). I don't know about these video things - if you watched it, is it helpful? Note to me: computer hutch, right side top shelf I normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box.
