Note 1
(1) Voltage, current, resistance source:(±0.001%RD+0.0015%FS)/°C.
Note 2
(1) Millivolts source: Max load capability is 1mA, load variance ratio less than 50 mA.
(2) 12V source: Max load capability is 5mA, load variance ratio less than 1mV/mA.
(3) Current source: Internal 24V power supply, max load capability is 20mA@1k Ω . External power supply, the max voltage is 36V.
(4) Simulating resistance: (1Ω to 110Ω) excitation current (0.6mA to 4mA), (110Ωto 400Ω) excitation current (0.3mA to
4mA), (400Ω to 1000Ω) excitation current (0.06mA to 1.5mA), (1000Ωto 4000Ω) excitation current (0.01mA to 0.6
mA). For (1Ω to 400Ω) range, 1mA driving current is recommended, and for (400Ω to 4000Ω) range, 0.1mA driving
current is recommended.
(5) , : ( )% , ,
(6) Loop 24V DC power: The maximum load current is 50mA, ripple<50mV.
(7) Simulating thermocouple, RTD source: To be decided by the accuracy of mV source and resistance source, according to
the ITS-90.
(8) All ports are short circuit protected.
(9) The maximum overvoltage of all the sourcing ports is±30VDC (less than 1 minute duration), the calibrator will be damaged
if this range is exceeded.
