16) Drift can be approximated by simple drift in the Range Zero Error. In reality all three terms in the
equation above can have drift.
17) The Current-to-Voltage converter bandwidth is a function of the current range, the cell cable, and the
IEStability setting. The bandwidth can be very low on very sensitive ranges. Longer cell cables add
capacitance and slow the current measurement.
18) The total error in a voltage setting is:
Error = DC Zero Offset + Gain × Voltage Setting
For a 1 V signal the theoretical error can be as high as 3 mV. In practice the error is generally less than
1 mV.
19) This specification is guaranteed by design. It is not tested.
20) This specification is measured by applying zero voltage across a 1 Ω resistor and measuring current
noise on the 600 µA scale. One µV of voltage noise creates a current of 1 µA. The filters in the ADC
Chain for the I Signal are used to limit the bandwidths as shown in the specification.
Signal-averaging via Gamry DSP mode further reduces the measured noise.
21) See Appendix D.
22) Isolation quality has both DC factors and AC factors (predominately at the 600 kHz power-supply
frequency). Only the DC leakage current is shown here. Consult Gamry technical support for
additional information.
23) Excluding external power adapter and any cables supplied with unit.
24) Excluding removable line cord.
