Specifications are typical values for 200uA and 2mA, 2A and 10A ranges when frequency >1kHz.Frequency and Period CharacteristicsFunctionFrequency, PeriodMeasuring CharacteristicsMeasuring CharacteristicsMeasuring CharacteristicsCapacitance CharacteristicsTemperature CharacteristicsFrequency and PeriodMeasurement MethodInput ImpedanceInput ProtectionCapacitance MeasurementMeasurement MethodConnection TypeApply constant current into the capacitance, and measure the voltage changing rate.2-wireMeasurement ConsiderationsSince small capacitance measurements are susceptible to the external noise, shielding inputs from external noise pickup is critical for minimizing measurement errors.FunctionCapacitanceRange[2]2.000nF20.00nF200.0nF2.000uF20.00uF200.0uF2.000mF20.00mF100.0mFTest Current200nA2uA10uA100uA1mA1mA1mA1mA1mA1 Year TCAL?±5?2 + 2.51 + 0.31 + 0.31 + 0.31 + 0.31 + 0.31 + 0.31 + 0.33 + 0.2Temperature Coefficient0? to (TCAL?-5?)

Shielding inputs from external noise pickup is critical for minimizing measurement errors. Settling Time ConsiderationsErrors will occur when attempting to measure the frequency or period of an input following a dc offset voltage change. Make sure the RC circuit of input terminal has been fully settled (about 1s) before accurate measurement.Reciprocal-counting technique, AC-coupled input using the AC voltage function.1 MO ± 2% in parallel with < 150 pF capacitance on any range750 V rms on all rangesAccuracy Specifications: ± (% of reading + % of range)[1][2]Accuracy Specifications [1][1] Specifications are for 90 minutes warm–up and using REL operation. Additional errors may be caused by non–film capacitors.[2] Specifications are the 1% to 110% of range on 2nF range and 10% to 110% of range on all other ranges.[1] Specifications are for 90 minutes warm-up. Exclusive of sensor error.[2] Specification is for 4WR sensor measurement or 2WR measurement using REL operation.FunctionTemperatureMeasurement ConsiderationsThe built-in cold junction temperature tracks the temperature inside the banana jack. The change of the temperature in banana jack might cause additional error. When using the built-in cold junction compensation, connect the sensor terminal of the thermocouple to the banana jack and warm it up for more than 3 minutes to minimize the error.Probe TypeRTD[2](R0 is within 49 O and 2.1 kO)Thermal ResistanceThermocouple[3]Typea = 0.00385a = 0.00389a = 0.00391a = 0.003922.2 kO3 kO5 kO10 kO30 kOBEJKNRSTOptimum Range-200? to 660?-200? to 660?-200? to 660?-200? to 660?-40? to 150?-40? to 150?-40? to 150?-40? to 150?-40? to 150?0? to 1820?-270? to 1000?-210? to 1200?-270? to 1372?-270? to 1300?-270? to 1768.1?-270? to 1768.1?-270? to 400?1 YearTCAL? ± 5?0.16?0.17?0.14?0.15?0.08?0.08?0.08?0.08?0.08?0.76?0.5 ?0.5 ?0.5 ?0.5 ?0.5 ?0.6 ?0.5 ?Temperature Coefficient0? to (TCAL?-5?)(TCAL?+5?) to 50?0.01 ?0.01?0.01?0.01?0.002?0.002?0.002?0.002 ?0.002 ?0.14 ?0.02 ?0.02 ?0.03 ?0.04 ?0.09 ?0.11 ?0.03 ?[3] Relative to cold junction temperature, accuracy is based on ITS-90.
