• Non-operating Random Vibration: 5 Hz to 500 Hz, 2.4 grms (exceeds MIL-PRF-28800F Class 3)
Electrical Protection
• Input to GND: ±30 VDC
• TC+ to TC–: ±30 VDC
– Key Features
• Compatible with 4-wire resistance and 2-wire voltage calibrators
• High-impedance source connection capability (Sense+/Sense–)
• 15-minute recommended warm-up time for measurement stability
• 1-year calibration interval
– Compatibility & Integration
The CAL-4353 connects directly to 4-wire resistance and 2-wire voltage calibrators. In certain configurations, TC+ and Sense+ or TC– and Sense– may be internally shorted; the accessory is not protected against faults between these pairs. High-impedance sources must connect only to Sense+/Sense– terminals.
Regulatory Compliance
Meets EN 61326-1 (Class A emissions; Basic immunity), EN 55011 (Group 1, Class A), and AS/NZS CISPR 11 (Group 1, Class A).
