条件：other functions or ranges. The additional error will generally dissipate within a few minutes.
Applying high-power signals (more than 300 Vrms, 500 VDC
1 A DC, or 1 Arms) can cause self-
heating in the signal-conditioning components. These errors are included in the instrument
specifications. Internal temperature changes due to self-heating may cause additional error on
Errors will occur in ACV and Frequency functions when attempting to measure an input following a
DC offset voltage change. The input blocking RC time constant must be allowed to fully settle (up
to 1 second) before the most accurate measurements are possible.
条件：4. For power- line frequency ±1%, the NMR is 40 dB. For ±3%, use 30 dB.
Reading settling times are affected by source impedance, cable dielectric characteristics, and
thermal EMF of connections. Keysight recommends using PTFE or other high-impedance, low-
dielectric absorption wire insulation for these measurements. To maintain low thermal EMF,
connectors and wires made of copper are recommended. 1. Applicable to ±100% of the range. 2. Applicable to >= 0.06 NPLC. 3. For power- line frequency
