3.1.2 Test range
Measurement range should be selected in accordance with the impedance value
of the tested LCR component.
TH2827 has 9 AC measurement ranges: 10, 30, 100, 300, 1k, 3k, 10k,
30k, 100k.
TH2827 has 13 DCR measurement ranges: 100m, 300m, 1, 10, 100,
300, 1k, 3k, 10k, 30k, 100k, 300k, 1M.
Operation steps for setting test range:
1) Move the cursor to the range zone, the following soft keys will be displayed:
 AUTO The soft key is used to set the range mode to AUTO.
 HOLD The soft key is used to switch the AUTO mode to the HOLD mode.
When the range mode is set to HOLD, the range will be locked in the
current measurement range. The current measurement range will be
displayed in the range zone.
 ↑(+) The soft key is used to increase the range under HOLD mode.
 ↓(-) The soft key is used to decrease the range under HOLD mode.
2) Use soft keys to set measurement range.
3.1.3 Test frequency
The measurement range of TH2827 ranges from 20Hz to 1MHz with an increase
or decrease of 0.01Hz. When the test function is set as DCR, the FREQ zone will
display “---”.
Frequency of TH2827A: 20Hz~300kHz
Frequency of TH2827B: 20Hz~500kHz
Frequency of TH2827C: 20Hz~1MHz

Operation steps for setting test frequency:
TH2827 provides two methods to set measurement frequency. The first one is to
use soft keys and the other one is to input data by using numeric keys.
1) Move the cursor to the FREQ zone, the following soft keys will be displayed.
 ↑(++)
This is a coarse adjustment soft key used to increase the frequency. Press
