Use the frequency counter for low voltage applications. Do not use the frequency
counter on AC power line systems.
• Five ranges:
120.000 mV, 1.20000 V, 12.0000 V, 120.000 V, 750.00 V—range is
based on the voltage level of the signal, not frequency.
• Measurement method:
Reciprocal counting technique
• Signal level:
10% of range to full scale input on all ranges
• Gate time:
0.1 s or 1 period of the input signal, whichever is longer
• Input protection:
750 V RMS on all ranges
