Jump (Range Skipping) - UNI-T UTE310 User Manual

User's Manual
time, set the scaling coefficient of CT to 0001.000, VT sets to 0001.000, and PT sets to 4000.000. During
the measurement, the secondary side of the ZCS400 will be output the scaled current. Connecting the
secondary side of the ZCS400 to the instrument's current input terminals, and the secondary side of the
VT connect to the voltage input terminals, at this time, the instrument displays the current of 0.19A, the
voltage of 300V and the power of 228kW. The displayed voltage and current are the actual values of the
input terminal, and the displayed power is the actual power in the measured line.
Cautions
1. When only using the scaling ratio function, please disable the EXT CH. Otherwise, the current value
displayed by the instrument is the signal collected from the EXT CH interface.
2. When using VT and CT at the same time, if user need to check the actual power and the actual
output value of VT and CT, the coefficient of VT and CT should be set to 1, and set the coefficient of
PT equal to the multiplied results of VT and CT.

6.5 JUMP (Range skipping)

UTE310 has multiple ranges for voltage and current. When selecting automatic range measurement, the
instrument will switch ranges one by one until it switches to the appropriate range. If the input signal
amplitude is large, or the input suddenly jumps from a large amplitude signal to a small amplitude signal,
switching the ranges one by one will take more time to wait and during the waiting period, important
measurement data may be lost.
The user can configure the range. When the auto-range measurement is activated, the instrument will skip
the unused ranges, thus minimizing the loss of measurement data due to range-by-range switching. This
function is disabled by default and will be effective only after it is enabled. The peak-over range jump can also
be set, when the peak of the measured signal exceeds 300% of the rated range (600% when CF=6 or 6A), it
will be prioritized to jump to the range set by the user, and after jumping, if the range is not the optimal range,
it will be switched again until it is switched to the optimal range.
Pressing the [Setup] key in any interface to enter the Setup menu, and press the function key JUMP below
the screen to enter the JUMP menu, and then use the [▲], [ ▼ ], [ ] or [ ] key to select or switch to the
parameter setting, as shown in the following figure.
