REAR VIEW OF TESTER CASEH261 temperature indicator testerIn testing D’Arsonval indicators, the H261 simulates thermocouple signals for testing 8, 15, 22 and 25 ohm indicators.
The unit is furnished with an input test terminal block for measuring cold junction temperature, so that any of four thermocouple types can be measured or simulated directly in °C. Additionally, 0 to 25.00 linear mV can be measured or simulated.
Four thermocouple curves are available for testing D’Arsonval or servo type indicators:
K CR/AL®1 (range: –200 to +1400 °C)
TF-30 (range: –10 to +1500 °C)
J FE/CON (range: –100 to +760 °C)
T CU/CON (range: –100 to 400 °C)
