Hi, I have been getting error 706 whenever I calibrate ACI. 706 read: Cal value out of range The specified calibration value (CALibration:VALue) is invalid for the present function and range. Calibration requires setting the function before entering calibration. Menu F: 2:calibrate and the meter responds with 1.000,000 AAC. Supposedly you are to apply 1 amp ant 1000 hz and press enter. No matter what values I use or even change the 1.000 to some other value I always get error 706 and the scale factor does not change. Is there a way to calibrate the AC current without changing the shunt resistor. The shunt resister is 0.1 ohms at 1% yet the meter is to deliver 0.1% ACI. Any ideas? -- John Phillips
