A 1179, A 1257, A 1395 Flex current clamps
15
1: Limits of bandwidth corresponding to a relative gain > - 3 dB
2: Reference conditions: 45 Hz – 65 Hz, conductor is in the center and preipedicular to
the measuring head, temperature between 15 ºC to 25 ºC; 10 k of load impedance;
laboratory environment electrical noise free.
3: Error of reading in reference conditions.
4: Expression of error measurement in refence conditions
error % = ( Iresidual / I measured ) x 100 + linearity + Accuracy
5: Full charged NIMiH 2200 mAh at 25 ºC
6: Distance between cable and clamp coupling should be 25 mm (1").
7: Adjacent conductor ≥ 20 cm or 8 inch from head. (<40 A/m)
8: This data can be changed regarding the temperature ranges of the used batteries.
9: No additional error in range 15 ºC – 25ºC,
for higher temperatures: Temp. error = (Temp - 25ºC ) * Temperature dependency
for lower temperatures: Temp. error = (15ºC - Temp ) * Temperature dependency
