RECORD Mode

Sample Rate 50ms Accuracy CREST mode where ±10 digits (±40 digits for AC signals) are added to the measurement function accuracy at 23°C ±5°C when the signal has fluctuated for 200ms or longer or the auto range has required 1.5 sec. or longer (except for the electrostatic capacitance and (DC + AC) voltage measurement). Accuracy ±220 digits are added to the measurement function accuracy at 23°C ±5°C applied to signal fluctuation of 0.8ms or longer.

CREST Mode

Accuracy ±220 digits are added to the measurement function accuracy at 23°C ±5°C applied to the signal fluctuation of 0.8ms or longer.

SORT Mode

Sort Time approx. 0.2 sec. (except for electrostatic capacitance and (AC/DC) voltage measurement) Accuracy ±5 digits are added to the measurement function accuracy at 23°C ±5°C.

Functions

3.5- or 4.5-digit display approx. 5 times per second when the display is 3.5-digit, 4,000 approx. 1.25 times per second when the display is 4.5-digit, 40,000 Hold Function to hold measurement operations at all measurement functions Manual or auto range Manual range selection Auto range selection Note: These functions are canceled when the measurement range is manually switched in the RECORD, CREST, SORT, hold, recall, or relative mode. Data store and recall You can store all display data in the memory and recall it later. Saved data can be called from other functions. Relative mode Relative mode can be selected from three operation methods. (1) D operation The relative value from the reference measurement value is displayed. The operation expression is "Display value = measurement value - reference measurement value". (2) Percent operation Measurement value is operated with respect to percentage to the reference measurement value and is displayed. The operation expression is "Display value = (measurement value - reference measurement value)/reference measurement value x 100 (%)". In this operation, the center of the bar graph is 0% and full scale display of ±200% or ±20% is used. (3) UNIT operation The rate of measurement value versus the reference measurement value is displayed as a positive integer. The operation expression is "Display value = measurement value/reference measurement value (UNIT)". RECORD mode The maximum and minimum measurement values are always saved in the internal memory. All sequential measurement values are calculated without the time restriction to derive the average value. When the 40000 button is held for one second or longer, the symbol "R" appears on the LCD display section and the RECORD mode is set. CREST mode You can measure the peak value of an instantaneous signal that is 0.8ms wide. When the 4000 button is held for one second or longer, the symbol "C" appears on the LCD display section and the CREST mode is set. SORT mode An alarm sounds when the measurement value is stable for about 0.2 second and the maximum, minimum, maximum minus minimum, and average values are calculated and recorded. Backlight function Alarm mute function Selection of the line frequency from 50Hz or 60Hz (Note: Always set this value before measurement because this reduces the influence of hum noise from the commercial power supply frequency on measurement values.) Auto power off (APO) Input alert RS mode (Data transfer only. Remote control function not available.)
