KEITHLEY 155 Null Detector-Microvoltmeter

The Keithley 155 Null Detector/ Microvoltmeter is a high-performance, low-cost instrument with better than 150nV resolution and full-scale ranges up to 1kV. Its electrical and physical ruggedness, broad range, and high common- and normal-mode rejection make it one of the most versatile voltmeters available for applications in standards labs, development labs, production testing, and basic research. RANGE: ±1µV full scale to ±1000V on zero center meter in 19 overlapping 1× and 3× ranges. Battery powered. ±2% of full scale. Common Mode Rejection is equivalent to 140 dB. Input resistance 100 Mohms, 3-1 kV range.

*This is a Web introductory price for one calibration of the KEITHLEY 155. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
