87. Rear input terminals only.
88. Specified for square wave inputs. Input signal must be >10% of ACV range. If input is<20mV
on the 100mV range, then the frequency must be >10Hz. For sine wave inputs, frequency
must be >100Hz. For frequencies ≤100Hz, threshold level ≤50% of input signal and ≤7Hz,
threshold level ≤3% of range.
89. Threshold range is voltage RMS and threshold level voltage peak. Specified with 1kHz square
wave. 100V and 700V threshold ranges guaranteed by design.
90. Reading speeds for autozero off, fixed range, autodelay off. Offset compensation off and open
lead detector off where applicable.
91. Buffer measurements: For <0.2 PLC, multisample, single buffer transfer binary reading only.
92. PC measurements: For 1 and 0.2 PLC single reading and single transfer to computer (USB).
93. Reading rates using factory default operating conditions and autorange off, autodelay off.
Speeds include measurement and data transfer out of the USB. ≥1000 readings with binary
transfer over USB.
94. For bandwidth 300Hz, autozero off, 6½ digits at 1 PLC, 3½ digits at 0.0005 PLC.
