Specification

Display	0 - 9999, red or green LED (character height 15 mm), “-” polarity, with zero-suppress function. During the measuring mode, the display switches from current value to peak memory, bottom memory, display amplitude, and current value. ''PM'' illuminates at peak memory display, ''BM'' illuminates at bottom memory display, both ''PM'' and ''BM'' illuminates at display amplitude display.
Decimal point indication	Arbitrary position by setting from the front panel and the rear terminals
Over-range display	Flashes at 130 %, but blinks ''0000'' when exceeding ''9999''. Flashes at full scale value when exceeding ''699'' for model 4256-06 Flashes at full scale value when exceeding 9 V for model 4256-26.
Scaling function	Full-scale display: -9999 to +9999 (0 to +9999 for the AC input type) Offset display: -9999 to +9999 (0 to +9999 for the AC input type)
Resolution	1/10000
Sampling rate	15 times / s
Display cycle	with selectable function from 67ms, 400ms, 1s, 2s, 4s, 5s
Input response	within 2 samplings or within 1-display cycle, whichever longer
Input method	Single ended, floating input
A/D conversion	⊿-∑ conversion method
Noise Rejection	Normal mode (NMR) – More than 50 dB. Common mode (CMR) – More than 110 dB. Noise through power supply line – 1000 V (at AC voltage power supply)
Comparative digit	Figure: 4-digit, Pole: 1-digit
Comparative method	2-isolated contact, programmable of high/low point (for model HI, GO, and LO) CPU comparative judgement method (against display value)
Setting method	by Digital switch setting
Width of hysteresis	1-999, set the same value for 2-comparative output
Comparative display	LED display, HI(red), GO(green), and LO(yellow)
Comparative output	Relay contact, 1-SPDT Hi and Lo, 250 V 1 A AC (resistive) NPN Open collector, Max. DC 30 V 30 mA, Max. 1.6 V saturation voltage
Delay output	ON delay, 0 to 60 seconds, arbitrary setting by 1 second step from the front switch (set the same value for 2-comparative output)
Hold	Hold for the measuring data, comparative output, and data output
Reset	Default the comparative output (break)
Insulation Resistance	DC 500 V, More than 100 MΩ
Withstand Voltage	Input terminals – External case: AC 1500 V each for 1min. Power supply terminals – External case: AC 1500 V each for 1min. Power supply terminals - Input and output terminals: AC 500 V each for 1min.
Power Supply	AC 100 to 240 V (50/60 Hz), DC 12 to 24 V
Power Consumption	Approx. 5 VA at AC 100 V, 7 VA at AC 200 V, 180 mA at DC 12 V, 90 mA at DC 24 V.
