SPECIFICATION (con’t)
mV OUTPUT: Non-linearized, cold-junction compen-
sated, amplified thermocouple output
(Not isolated from selected TC input.)
On ºC Scale:
1mV/ºC on 200º range
0.1mVºC on 760º range
0ºC = OmV output
On ºF Scale:
5/9 mV/ºF on 200º range
5/90 mV/ºF on 1400º range
0ºF = OmV output
mV OUTPUT ACCURACY
(18º - 28º C)
±(5% + 1mV) on 200º ranges;
±(5% + 0.1mV) on High ranges
Includes TC non-linearity, excludes TC
errors. Output resistance: 10k ohms
mV OUTPUT TEMPERATURE
COEFFICIENT (0º - 18ºC
& 28º - 50°C)
Less than (0.1 x accuracy specification)/ºC
mV OUTPUT PROTECTION: 35 V dc (42 V peak) max; +mV to -mV and
selected thermocouple input to +mV or -mV.
THERMOCOUPLE LINEARIZATION: Multi-scope A/D with nine piecewise linear
segments between -40º and 760º C
