Manual span adjustments: 95 to 105 %

(factory setting: 100 %)

Programming: Downloaded from PC; T/C type, temp. range,

output range, zero and span, simulating output, user's

temperature table, linearization, etc.

Burnout protection: Upscale standard; downscale or no

burnout optional by programming

(Set to "no burnout" when the unit is connected with

another instrument in parallel.)

Cold junction compensation: CJC sensor attached to the

input terminals

Status indicator LED: Blinking patterns indicate different

operating status of the transmitter.

Configurator connection: 2.5 dia. miniature jack;

RS-232-C level

INPUT SPECIFICATIONS

Input resistance: 1 MΩ min.

Burnout sensing: 45 nA ±10 %

Minimum span: 20°C or 36°F

Offset: Lower range can be any specific value within the

input range provided that the minimum span is maintained.

For temperatures ranges near lower limit of the usable

range, the transmitter may not satisfy the described

accuracy. Consult M-System.
