4.2.3 Frequency setup
TX7410 has the following test frequencies: 50Hz, 60Hz, 100Hz, 120Hz, 1kHz, 10kHz,
20kHz, 40kHz, 50kHz, 100kHz.
Press FREQ key, and the frequency changes among the foregoing frequencies.
Or
press
PREQ,
then
▲、▼
to switch parameter.
And the current frequency is displayed in frequency area on LCD.
4.2.4 Signal voltage
TX7410 has the following 3 common signal voltages: 0.1V, 0.3V, 1V
Press LEVEL key, and the level changes.
Or press
LEVEL,
then
▲、▼
to switch level.
And the current voltage is displayed in voltage area on LCD.
4.2.5 Measurement speed
TX7410 has 3 measurement speeds available: F (fast), M (middle), S (slow).
Fast: about 20measurements/second.
Middle: about 10measurement/second.
Slow: about 2measurements/second.
Press SPEED key, and the speed changes.
Or press
SPEED,
then
▲、▼
to switch speed.
And the current measurement speed is displayed in speeda area on LCD in the form of F, M
or S.
4.2.6 Trigger
When the trigger mode is set manual, the instrument performs one measurement by
pressing TRIGGER key once.
4.2.7 Range setup
TX7410 totally has 9 ranges: 10Ω, 30Ω, 100Ω, 300Ω, 1kΩ, 3kΩ, 10kΩ, 30kΩ, 100k. Please
select range accoding to the impedance of the device under test.
Please refer to the following table for range and its corresponding measurement range.
When the instrument is working at automatic range, it can look for the most suitable range
to take measurement, therefore, it’s recommended to select range auto mode mostly, to
avoid incorrect measurement caused by wrong selection of range.
But in some special cases, range should be held, such as measurement of the same type in
batch and sorting test, in order to improve efficiency, speed and stability. Inductance’s bias
test should be performed at held range.
The way to hold range is to make instrument automatically measure, and hold range after
