Measurement Characteristics

Accuracy is ±(% reading + number of digits) at 23°C ± 5°C, less than 75% R.H.

(1) DC Volts(for 61-340 / 61-342)

	Range	Resolution	Accuracy	Over voltage
				protection
	400.0mV	0.1mV	±(0.8% reading + 3 digits)
	4.000V	1mV
	40.00V	10mV	±(0.8% reading + 1 digits)	1000VDC or 750VAC
	400.0V	100mV
	1000V	1V	±(1.0% reading + 3 digits)
Input Impedance: 10MΩ
(2) AC Volts (61-340/61-342)
	Range	Resolution	Accuracy	Over voltage
				protection
	400.0mV	0.1mV	±(1.2%+8)
	4.000V	1mV
				1000VDC or 750VAC
	40.00V	10mV	1.0% + 5
	400.0V	100mV
	750V	1V	±(1.2%+5)

Input Impedance: 10MΩ

AC Conversion Type: 61-340:Average sensing rms indication calibrated to the sine wave input. 61-342:AC conversion is True RMS responding, calibrated to a sinusoidal waveform

Crest Factor: C.F. = Peak/RMS

For non-sinusoidal waveform, C.F. > 2 add ±1% to accuracy,

Frequency response: 40～400Hz

(3a) DC micro-amp and milli-amps (for 61-340 / 61-342)
	Range	Resolution	Accuracy	Input Protection
	400.0µA	0.1μA	±(0.8% reading + 2 digits)*
	4000µA	1μA		500mA, 250V Fast
	40.00mA	10μA	±(0.8% reading + 3 digits)*	Blow Fuse
	400.0mA	0.1mA

Overload Protection: mA Input: 500mA, 250V Fast Blow fuse. (61-340 / 61-342)
