- The datasheet states the operating temperature range of the ODEN AT. Value: 0 °C to +50 °C (+32 °F to +122 °F).
- The datasheet states the output of an ODEN AT with one S current unit on the lowest mains voltage. Value: ODEN AT/1S at 240 V mains: 6 V open circuit voltage; 1000 A continuous; 2000 A for 3 minutes; 7000 A maximum.
- The datasheet states the output of an ODEN AT with three H current units in parallel on the highest mains voltage. Value: ODEN AT/3H at 480 V mains, units in parallel: 4.3 V open circuit voltage; 3800 A continuous; 7700 A for 3 minutes; 21 kA maximum.
- The datasheet states the phase angle range, resolution and inaccuracy of the ODEN AT. Value: 0 to 359°, resolution 1°, inaccuracy ±2° for readings above 10 % of the selected range.
- The datasheet states the timer ranges and inaccuracy of the ODEN AT. Value: 0.000 to 999.9 s; 0 to 9999 cycles; 0.001 s to 99 h 59 min; inaccuracy ±(1 digit + 0.01 % of value).
- The datasheet states the voltmeter ranges and inaccuracy of the ODEN AT. Value: 0 to 9.999 V; 10.00 to 99.99 V; 100.0 to 200.0 V; inaccuracy 1 % of range ±1 digit.
- The datasheet states the weight of each unit of the ODEN AT system. Value: control unit AT 25 kg (55 lbs); current unit S 42 kg (92.6 lbs); current unit X 45 kg (99.3 lbs); current unit H 49 kg (108 lbs); cart 11 kg (24.3 lbs).
- The datasheet gives the mains inlet of the ODEN AT as a connector to IEC 60309-2 and gives no edition. Value: IEC 60309-2.
- The catalog name of the model is written Megger ODEN AT. Value: Megger ODEN AT.
