Digital Milli Volt and Milli-Amp Source and Meters
Product Code : JA-DMI-1034
The Digital Milli Volt and Milli-Amp Source and Meters (SKU JA-DMI-1034), supplied by JaincoLab, is a thermocouple calibrator that gives continuously variable DC outputs of 0 to 200 mV and 0 to 200 mA. The output wanted is chosen on the front panel and shown on a 3.5 digit display. The voltage source impedance is 2 ohm, and the built-in DVM has an input impedance above 10 megohm.

Frequently asked questions
What outputs does this source give?
Continuously variable 0 to 200 mV DC and 0 to 200 mA.
Why is it called a thermocouple calibrator?
Its 0-200 mV output covers the range of thermocouple signals, so it can stand in for a thermocouple when checking instruments.
What is the source impedance?
2 ohm for the voltage source; the DVM input impedance is above 10 megohm.
