Explanation
Measurement Range
• The measurement range varies depending on the display update rate (see section
4.13) as follows:
Display Update Rate Measurement Range
0.1 s 25 Hz to 100 kHz
0.25 s 10 Hz to 100 kHz
0.5 s 5 Hz to 100 kHz
1 s 2.5 Hz to 100 kHz
2 s 1.5 Hz to 50 kHz
5 s 0.5 Hz to 20 kHz
• There are six types of measurement ranges, 1 Hz, 10 Hz, 100 Hz, 1 kHz, 10 kHz,
100 kHz. The measurement range switches automatically.
Maximum Reading, Unit, and Unit Prefix
• Maximum reading: 99999 (when the number of displayed digits is 5)
• Units: Hz
• Prefix: k
