3.1.2 Test range
Measurement range should be selected in accordance with the impedance value
of the tested LCR component.
U2836 has 5 AC measurement ranges: 30
Ω , 100 Ω , 1k Ω , 10k Ω and 100k Ω .
When the output impedance is selected as 30 Ω and 50 Ω , U2836 has 6 AC
measurement ranges: 10 Ω , 30 Ω , 100 Ω , 1k Ω , 10k Ω and 100k Ω .
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.
„ INCR
+ The soft key is used to increase the range under HOLD mode.
„ DECR
- 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 U2836 ranges from 50Hz to 200kHz, total 37
frequency points.
Operation steps for setting test frequency:
U2836 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.
„
INCR
++
This is a coarse adjustment soft key used to increase the frequency. Press
this key, the frequency will change as the following sequence: 50Hz,
100Hz, 1kHz, 10kHz, 100kHz, 200kHz.
„
INCR
+
This is a fine adjustment soft key used to increase the frequency. Press
this key, the frequency will switch between the following ones:
50 Hz 100 Hz
1 kHz 10 kHz 100 kHz
60Hz 120 Hz 1.2 kHz 12 kHz 120 kHz
80 Hz 150 Hz 1.5 kHz 15 kHz 150 kHz
200 Hz 2 kHz 20 kHz 200 kHz
250 Hz 2.5 kHz 25 kHz
300 Hz 3 kHz 30 kHz
400 Hz 4 kHz 40 kHz
500 Hz 5 kHz 50 kHz
600 Hz 6 kHz 60 kHz
