*1Negative values can be up to 10% of positive full scale.
*2Measurement current accuracy is ±5%.
*3Voltage when not measuring is 20 mV or less, with current mode set at PULSE and Contact Improver Setting set at OFF/PULSE (with a voltmeter having 10 MΩ).
*4VOLTAGE LIMIT ON: 10 V max
*5With the sum of resistances of the probes, sample, and contacts less than (open-circuit voltage) / (measurement current).
Example. 100 mA measurement current can be used when the sum of resistances of the probes, sample, and contacts is no more than 20 Ω.
