Technical Data | Environmental Specifications * | Operating Temperature: -10¨¬C to 50¨¬C (-20¨¬C typical except for frequency and ac voltage measurement) Storage Temperature: -20¨¬C to 60¨¬C Operating Altitude: 2800m above mean sea level (9186 ft) Enclosure Protection: Designed to meet IEC529 IP52 (normal operating vacuum for dust) | Data Log Function | Measure functions: Voltage, current, resistance, frequency, temperature, pressure Reading rate: 1, 2, 5, 10, 20, 30, or 60 readings per minute Maximum record length: 8000 readings (7980 for 30 or 60 readings per minute) | Ramp Function | Source functions: Voltage, current, resistance, frequency, temperature Rate: 4 steps/second Trip Detect: Continuity or voltage (continuity detection not available when sourcing current) | Loop Power Function | Voltage: Selectable, 24V or 28V Accuracy: 5% Maximum current: 22 mA, short circuit protected Maximum input voltage: 30V dc | *(all calibrator specifications apply from +18¡ÆC to +28¡ÆC unless stated otherwise)
General Specifications | Dimensions | 130 x 236 x 61 mm | Weight | 1.4 kg (3 lb 1 oz) | Internal Battery Pack | NiMH 7.2V, 3500 mAh | Battery Life | Typical usage > eight hours | Battery Replacement | Via snap-shut door without opening calibrator; no tools required | Side Port Connections | - Pressure module connector
- RS-232 connector to interface to your PC
- Connection for optional battery eliminator
| Safety | Complies with CAN/CSA C22.2 No 1010.1-92, ASNI/ISA S82.01-1994, UL3111, and EN610-1:1993 | Data Storage Capacity | 1 week of calibration results | 90 day specifications | The standard specification intervals for the 744 is 1 and 2 years. Typical 90 day measurement and source accuracy can be estimated by dividing the one year "% of reading" or "%of output" specifications by 2. Floor specifications, expressed as "% of f.s." or "counts" or "ohms" remain constant. |
