Speeds are for 60Hz operation using factory default operating conditions (*RST). Autorange off, Display off, Trigger delay = 0. Speeds include measurement and binary data transfer out the GPIB. 1 PLC = 16. 67ms @ 60Hz, 20ms @ 50Hz/400Hz. The frequency is automatically determined at power up. For signal levels >500V, add 0. 02ppm/V uncertainty for the portion exceeding 500V. Must have 10% matching of lead resistance in Input HI and LO. For 2-wire ohms, add 1Ω additional uncertainty. For rear inputs, add the following to temperature coefficient “ppm of reading” uncertainty 10MΩ 95ppm, 100MΩ 900ppm. Operating environment specified for 0º to 50ºC and 50% RH at 35ºC.
