Tonghui TH2840 Series - Frequency, Voltage, Switch and Scanning Sequence; TURN Test Conditions Setup

81
7.11.1 Frequency, voltage, switch and scanning sequence
There are multiple parameter variables corresponding to each parameter: frequency, level, deviation,
average, delay, equivalence, scan sequence and switch. Touch or move the cursor to the
corresponding setting area and modify the corresponding parameters according to the menu prompts
to meet user needs.
Note:
 Frequency range: 20Hz～2MHz.
 Test level: 5mV～20V.
 Deviation: Off, Δ%; this parameter is used to set the sorting method, the same as the limit
mode of TH2829X series.
OFF: The test results are sorted directly according to the set upper and lower limits.
Δ%: The difference between the test value and the nominal value divided by the nominal value will
be sorted according to the set upper and lower limits.
 Average times: 1～255. Perform multiple tests according to the set average times, and display
the results after calculating the average value. This function can also be used to adjust the test
speed of a single parameter.
 Delay: 0～60s, the delay between the trigger test and the test. This function can improve the
stability and accuracy of the test.
 Equivalence: series, parallel.
 Sequence: the default number of the scanning sequence is 1-9 from left to right, you can enter
the number 1-8 to change, and BAL is fixed as the last item 9.
 Switch: If you choose to ON, the corresponding parameter is valid, otherwise the
corresponding parameter is invalid.
7.11.2 TURN Test Conditions Setup
On the <Trans Conditions> page, touch or move the cursor to the Turn column of the test condition
table to set the Turn parameters.
