1.3 Feature Set The SMX2055 is a traditional 5-1/2 digit DMM and it can be used as a general purpose DMM. The High Workload Multi Function SM2064 adds timing, capacitance, inductance, sourcing and a lot more speed. With its specialized measurements, it can replace some costly instruments, shrinking the size and cost of a test system. -

A common source of error can come from your test leads, which can introduce several Volts of error due to thermal voltages. To minimize thermal voltaic effects, after handling the test leads; you should wait a few seconds before making measurements. Signametrics offers several high quality probes that are optimal for low- level measurements. -

Page 57: Calibration
Keep in mind that for ranges and functions that are unavailable for a particular product in the SM2060 family. The following calibration record is for the SMX2055 and it contains some placeholders for ranges that are not available with the product. An example SM60CAL.DAT follows:... - Page 58 DMM followed by a value of 2/3 of the top of each range. Calibration of your SM/SMX2055/60/64 is best performed using calibration software available from Signametrics. When using multiple DMMs in a single chassis, the SM60CAL.DAT file must have a calibration record for each DMM.
