NOTES

86. Applies for non-sine wave inputs, DC content

≤3% of range, maximum crest factor ≤5.0. For bandwidth 30Hz, autozero off, 6½ digits at 1 PLC, 3½ digits at 0.0005 PLC.

87. Rear input terminals only.

88. Specified for square wave inputs. Input signal must be >10% of ACV range. If input is <20 mV on the 100 mV range, then the frequency must be >10 Hz. For sine wave inputs, frequency

must be >100 Hz. For frequencies

≤100 Hz, threshold level ≤50% of input signal and ≤7 Hz, threshold level ≤3% of range.
