3.2 Ratio Measurements (DC Voltage only)
This function calculates the ratio of an input DC voltage to a reference DC
voltage according to the following equation:
※
Note: This function only applies to DC voltage measurement.
How to make a ratio measurement
There are two ways to make a ratio measurement: Through the front
panel operation or through the remote interface operation.
Front Panel Operation
1.
Connect the test leads to the terminals on the front panel.
2.
Press DCV button to select DC voltage measurement.
3.
Press CONFIG, and then use
◁
and
▷
buttons to locate “RATIO”
option.
4.
Press ENTER to select it.
5.
Connect test leads from the “INPUT HI & LO” and the “SENSE HI &
LO” to your source signal and observe readings.
※
Note: To turn off this function, please press one of the measurement
function buttons.
※
Note: RAT anunciator will lit when Ratio measurement is on.
3.3 Current Measurements (DC & AC)
The ranges for DC current measurements in M3510A/11A are 10mA,
100mA, 1A,
3A
and 10A. For AC current measurements, the range is 1A
with sensitivity of 1 nA to 10A AC-Coupled TRMS with sensitivity of 10µA.
Warning! To avoid damaging the fuse of current input.
Under current measurements, the input source below 3 A or between
