1.For DC:technical indicators are valid after 60 minutes of preheating, set to 10 or 100NPLC in the integral period, and enable automatic zero setting.For AC:technical indicators are effective when preheating for 60 minutes, using slow ac filter and sine wave
2.All ranges have 20% overrange except for 1,000DCV、750ACV、10ADC、3AAC、10AAC and diode testing.
3.Relative to the calibration standard
4.Outside of the range of TCAL±5℃,each degree（℃） increases a coefficient.
5.Technical indicators arei valid when sinusoidal wave is input >5% range and >1mVrms. The 750ACV range is limited to 8× 107v-hz.
For inputs within 1% and 5% of range and frequency<50 kHz, add 0.1% of range additional error. For 50kHz to 100kHz, add 0.13% of range additional error
6.Low frequency performance:three filter Settings are provided:3Hz、20Hz、200Hz.The frequency beyond the filter setting has been specified, no additional errors will occur.
7.Technical indicators are suitable for 4 lines or 2 lines measurement（peration bias returns to zero）resistance measurement.If there is no mathematical null, 2 lines resistance measurement will increase 0.2 Ω additional error.
8.The 10A range is provided on the front connector only.Each amplifier adds a 2mA base current value, or input current >5Arms.
9.Technical indicators are valid when sine wave is input >1.5% range and >10μAAC. 10.Technical indicators are suitable for the voltage measured at the input end.1mA test current is typical.The change of current source will lead to the change of voltage drop of diode junction
11.The selected probe limits the actual measuring range and measurement errors.Probe accuracy has included all measurement and ITS-90 temperature conversion errors.PT100Ro can be set to 100Ω±5Ω, to eliminate the original probe error.
12.Unless otherwise indicated, the technical indicators are valid after 60 minutes of warm-up and with sinusoidal input.Technical indicators are suitable for 1s gate time.(7 bits)
13.Suitable for sinusoidal and square wave input ≥100mV.For 10mV to 100mV inputs, multiply the reading error % by 10.
14.The range is 10% to 120% below 750ACV.
15.The square wave input is specified as 10Hz-300kHz.
