Description 

Factory 

Default 

PID I 

The integral term of the PID loop. Will only be 
available if 

Gain

 is set to 

PID

0.01 

PID D 

The derivative term of the PID loop. Will only 
be available if 

Gain

 is set to 

PID

.

 

Sensor 

Sets the temperature measurement sensor. 
Can be 

Therm 100uA or 

 

Therm 10uA

.

 

Therm 
100uA 

T-Low Lim 

T-Low Lim

 is the lower temperature limit. If 

operating in T Mode and the actual 
temperature drops below this value, the 
output will be turned off. Temperature limits 
not monitored in R Mode or Ite Mode. Limit 
monitoring can also be disabled in software 

(see TEC:ENAB:OUTOFF command). 

-99°C 

T-High Lim 

T-High Lim

 is the upper temperature limit. If 

operating in T Mode and the actual 
temperature rises above this value, the 
output will be turned off. Temperature limits 
not monitored in R Mode or Ite Mode. Limit 

monitoring can also be disabled in software 
(see TEC:ENAB:OUTOFF command). 

125°C 

R-Low Lim 

R-Low Lim

 is the sensor low limit. If 

operating in R Mode and the actual sensor 
measurement drops below this value, the 

output will be turned off. R limits are not 
monitored in Ite Mode. Limit monitoring can 
also be disabled in software (see 
TEC:ENAB:OUTOFF command). 

0.01k

 

R-High Lim 

R-High Lim

 is the sensor high limit. If 

operating in R Mode and the actual sensor 
measurement exceeds this value, the output 
will be turned off. R limits are not monitored 
in Ite Mode. Limit monitoring can also be 
disabled in software (see 

TEC:ENAB:OUTOFF command). 

45k

 

Tol Time 

Tolerance time is the amount of time, in 
seconds, that the actual temperature must be 
within the set point tempe/- the Tol 
Temp value for the unit to be considered in 
tolerance.
