7. Technical specifications are suitable for 4-wire or 2-wire resistance measurement (NULL return to zero). Without NULL resetting, 2-wire resistance measurements add an additional error of 0.2Ω.
8.10A range is only available on the front connector. Add 2mA base current value to each amplifier, or input current >5Arms. 9. The technical specifications are valid when the sine wave input is >1.5% range and >10μAAC.
10. Technical specifications apply to the voltage measured at the input end. 1mA test current is typical. The change of current source will cause the voltage drop of diode junction to change.

1. For DC: the technical indicators are valid after 60 minutes of preheating, the integration period is set to 10 or 100PLC, and automatic zero is enabled. For AC: The technical specification is valid after 60 minutes of warm-up, with slow AC filtering and sine wave.
2. 20% overrange for all ranges except 1,000DCV, 750ACV, 10ADC, 3AAC, 10AAC and diode tests.
3. Relative to calibration standards.
4. Outside the TCAL±5℃ range, a coefficient is increased for every 1 degree (℃).
5. The technical index is valid when the sine wave input is >5% range and >1mVrms. The 750ACV range is limited to 8×107V-Hz. If the input signal frequency is < 50KHz and the sine wave input is between 1% and 5% of the entire range, then the indicator needs to add an additional 0.1% extra error, and the frequency between 50KHz and 100KHz, the indicator needs to add an additional error of 0.13%.
6. Low frequency performance: provide three filter Settings: 3Hz, 20Hz, 200Hz. Exceeding the frequency set by the filter has been specified, and no additional error will occur.
7. Technical specifications are suitable for 4-wire or 2-wire resistance measurement (NULL return to zero). Without NULL resetting, 2-wire resistance measurements add an additional error of 0.2Ω.
8.10A range is only available on the front connector. Add 2mA base current value to each amplifier, or input current >5Arms. 9. The technical specifications are valid when the sine wave input is >1.5% range and >10μAAC.
10. Technical specifications apply to the voltage measured at the input end. 1mA test current is typical. The change of current source will cause the voltage drop of diode junction to change.
11. The selected probe will limit the actual measurement range and measurement error. Probe accuracy has included all measurement and ITS-90 temperature conversion errors. The PT100Ro can be set to 100Ω±5Ω to eliminate the original probe error.
12. Unless otherwise stated, technical specifications are valid after 60 minutes of warm-up and with a sine wave input. Technical specifications Applicable to 1s strobe time (7 bits).
13. Suitable for sine wave and square wave input ≥100mV. For input signals of 10mV to 100mV, multiply the indicator by 10 (i.e., enlarge the reading indicator by a factor of 10).
14. The amplitude range is 10% to 120%, less than 750ACV.
15. The square wave input is specified as 10Hz-300kHz.
