Command Reaction 
CALC:CONV:TEST?  <res> 
Returns the calculated temperature in Celsius for the given sensor 
reading, or “0.0,OL” if the result is out of range. The parameter <res> is 
the sensor reading in ohms.   
FETC? 
Returns the last measurement in units according to the UNIT:TEMP 
setting. If there is no valid measurement available the response is 
“0.0,OL”. 
SENS:DATA:OHMS? 
Returns the present ohms reading. The response is expressed in ohms. 
If there is no valid measurement available the response is “0.0,OL”. 
STAT:MEAS? 
Reads and clears the Measurement Event Register, indicating whether a 
new measurement is available to be read. Returns “1” if a new 
measurement has occurred since the previous command, and “0” 
otherwise. 
SYST:ERR? 
Returns a system error message if any are present in the system error 
queue. Otherwise it returns “0,”No error”’.

Returns the present state of password protection. The response is “1” if 
access to password-protected settings is allowed, or “0” if they are

SYST:PASS:NEW  <pass> 
Sets new password. The <pass> parameter is the new password. It can 
be up to 10 characters in length and can include any upper or lower

are automatically converted to upper case upon receipt and returned as 
upper case in any related query commands. IMPORTANT: Do not 
forget the password. 
UNIT:TEMP  <unit> 
Sets the temperature unit to degrees Celsius or Fahrenheit. The <unit> 
parameter is C for Celsius or F for Fahrenheit. If the SI unit lock is ON, 
only Celsius is allowed.
