Cross value
The area of this part is
the effective value (RMS).
In the above example, the effective value (RMS) can be obtained by specifying this cross value.
To obtain the cross value, specify the voltage crossing the waveform.
If the waveform uctuates up and down, check the waveform and set the cross value.
The operation method (of this device) is shown below.

Effective value (RMS)
By specifying the cross voltage value, you can calculate the effective value (RMS).

Setting Description
(1) RMS value operation
cross value
Set the voltage which is the ± cross value for performing the RMS operation.
(2) Get current measured
voltage value
The RMS operation cross value of (1) is calculateed automatically from the current input waveform.
(3) Cross value reset Reset the RMS operation cross value. (Set to 0V.)
When reading from the current measured voltage value, calculate after the actual input is entered.
Burnout check
Burnout refers to a state where the thermocouple is disconnected.
Check burnout of CH that is set to temperature.
Since the device cannot detect burnout and measure at the same time, check whether or not burnout has
occurred when measurement is not performed.
Please be aware that the measured value is not accurate when burnout takes place.
