All ac, Hz, and duty cycle are specified from 1 % to 100 % of range. Inputs below 1 % of range are not specified.

Typical burden voltage: DC/AC Current µA: 100 µV / µA; DC/AC Current mA: 2 mV/mA; DC/AC Current A: 0.03 V/A

Typically, open circuit test voltage is 2.0 V and short circuit current is <0.6 mA

Use Type K thermocouple

Typical open circuit test voltage is 0.54 V, maximum short circuit current is 1.8 mA

Specifications do not include errors due to test lead capacitance and capacitance floor (may be up to 1.5 nF in the 40 nF range).

Typical means when the frequency is at 50 Hz or 60 Hz and the duty cycle is between 10 % and 90 %.
