The HP 974A Multimeter has 4 1/2 digits with a dc accuracy of 0.05%,100 kHz BW true rms. ac+dc, and dB/dBm with 0.01 dB resolution make th is the best value for high precision. Min/Max with time stamp to monitor all types of measurements including temperature, Hold and Auto Hold for saving a reading manually or automatically and average to quiet noisy measurements. Auto diode reverses the leads for you to check semiconductor junction. a secondary digital display shows the range of the function or elapsed time in Min/Max, and auto power off turns off the meter after 30 minutes of inactivity, or defeat it for extended measurements.
