Output
OUTPUT1 ±10 V ±5 mA, OUTPUT2 ±10 V ±10m A
Output impedance: 0.5Ω or less, Capacitive load: Operable up to 0.1 μF
(For output current of 4 -
20mA: Load impedance: 500 Ω or less, Output
impedance: Approx. 5 MΩ, Voltage/current conversion accuracy: Within ±0.1%)
Output adjustment OUTPUT2 ADJ (Can be independently varied continuously from 1 to 1/10)
Output monitor
display
17-dot LED display (OUTPUT1 monitor)
Green LED at center blinks when voltage is within approximately ±100 mV.
LEDs at both ends blink when voltage is greater than approximately ±10.5 V.
Digital display
4 1/2 digital display (OUTPUT2 monitor), Scaling display available with
OUTPUT2 ADJ
Accuracy: Within ±0.05% rdg ±1 count, Displaying location of decimal point can
be changed by using the bottom setting SW.
Key lock function
Turning the key lock ON/OFF by pressing the key lock button approximately for
one second.
(Except CAL switch and BV selection switch)
Setting value saving Saving the value in flash memory. (Can be held without back-up battery)
