  Output: ±0.02 %/°C (±0.01 %/°F)
Response time: ≤ 0.4 sec. (0 – 90 %)
Burnout response time: ≤ 2 sec.
Insulation resistance: ≥ 100 MΩ with 500 V DC
Dielectric strength: 1500 V AC @ 1 minute (input to output to internal bus or internal power)
2000 V AC @ 1 minute (power input to FG; isolated on the power supply module)

STANDARDS & APPROVALS

EU conformity:
EMC Directive 
  EMI EN 61000-6-4
  EMS EN 61000-6-2
RoHS Directive

FUNCTIONS

• Zero/Span Adjustment Modes
Monitor Mode

Re-transmits the input signal as output in proportion.
Output 0 % Adjustment Mode
Adjusts the 0 % output signal using the front UP/DOWN buttons, in monitoring the output value with a multimeter.  SW1 through SW3 switch the internal increments by 1, 5 and 10.
Output 100 % Adjustment Mode
Adjusts the 100 % output signal using the front UP/DOWN buttons, in monitoring the output value with a multimeter.  SW4 through SW6 switch the internal increments by 1, 5 and 10.
Simulated Output Mode
Outputs the simulated signals of 0 %, 50 % and 100 %.
• How to Operate
1) Start up in Monitor Mode (SW position = 0) and wait for 2 or 3 seconds.
2) Switch to another mode and go through the adjustments.
3) Reset the switch to the position ‘0’ so that the new setting is stored in the internal memory.
