For the commands that acquire measurement values (:FETCH? and
:READ?), the response formats are as follows.
Measured resistance value
Measured voltage value
Relative value Indication (%)
(same as voltage and resistance)
• In fact, the “+” sign for the mantissa is returned as a space (20H).
• When a measurement fault occurs during voltage measurement in the 10 V
range, one more digit is increased (for the exponent) for the measured value
string than in other modes.
• Unneeded zeroes to the left of the decimal point are replaced by blank space
(20H).
Example : _0001.36E-3 → ____1.36E-3
-0007.51E+0 → -___7.51E+0
("_" indicates blanks space [20H].)
The response will take the form of
±*.*****E+3 at voltages of
-1000 V or less and 1000 V or greater.
