Stability of calibration in the IET Labs, GenRad 1864 megohm meter is maintained by use of a four-transistor unity gain amplifier. In addition, no warm-up drift is encountered, and high zero stability is maintained during operation. Human engineering has not been overlooked in the GenRad 1864 Megohm meter as evidenced by the warning light that is activated by the application of the test voltage. The 1864 employees a measure / charge / discharge switch and provision for performance grounded and ungrounded measurements.
