Note 3. Intrinsic standoff ratio, is defined in terms of peakpoint voltage, VP, by means of the equation: VP = VB2B1 VF, where VF is approximately 0.49 volts at +25°C @ IF = 10µA and decreases with temperature at approximately 2.5mV/°C. Components R1, C1, and the UJT form a relaxation oscillator, the remaining circuitry serves as a peakvoltage detector. The forward drop of Diode D1 compensates for VF. To use, the "call" button is pushed, and R3 is adjusted to make the current meter, M1, read full scale. When the "call" button is released, the value of is read directly from the meter, if full scale on the meter reads 1.0. Note 4. Use pulse techniques: PW 300µs, duty cycle 2.0% to avoid internal heating, which may result in erroneous readings.
