output to power

(for output code 5, L3 alarm output and L4 alarm output is

not available)

Burnout protection: Upscale standard; downscale or no

burnout optional by programming

(Set to "None" at item [74] Burnout, when the unit is

connected with another instrument in parallel.)

Cold junction compensation: CJC sensor attached to the

input terminals

Configuration: Program with front buttons or Via PC.

Programmable features include: Refer to the parameter list.

Configurator connection: 2.5 dia. miniature jack;

RS-232-C level
