7 / 22 page Ver 2.9 7 10/06/25 ES51925 3000 Counts Smart DMM 1.1.2 HCF detection ES51925 provides detection of high-crest-factor (HCF) signal in ACV auto range mode. ES51925 senses the signal and determines it as HCF if the Vpp is large enough. Once the signal is determined as HCF, ES51925 will jump up one measuring range regardless of current measurement value. It takes 60ms to jump one range up. The jumping up process will continue until the maximum range is reached. With HCF detection, a more accurate result could be obtained. For example, when a input signal with Vpp=200V, Vrms=40V(CF=5) was applied, traditional DMM might stay at 30V range but shows counts with the amount of error up to 10% or even bigger. The error rises from limited input/output swing at internal ADC. With HCF detection, DMM will stay at 300V range and exhibits more accurate results. 1.1.3 EF mode ES51925 supports a non-contact ac voltage measurement, which is called electric field measurement also. The EF mode is selected by SEL key when EF_EN is active. The ADC input is configured from ADP pin vs. SGND. When no or less electric field is detected, the LCD shows “EF”. If the detector senses electric field, the strength will be showed on LCD by “-“ not digits type. Level 1(weak) is “-“ and the level 4(strong) is “----“. Additional beeper will be output from BUZOUT pin. The buzzer frequency depends on the strength of electric field also. The Faster beeper means the stronger electric field (ac voltage) is sensed. |
