TH2829X Series Operation Manual Chapter 6 Transformer Single-machine Test
6.2.1 DELAY
Trigger delay means the delay time from trigger start to test start. Delay function
allows users to set the trigger delay time. When the instrument makes auto
sweep test for transformer parameters, at each sweep test point, the instrument
will trigger delay for preset delay time. The delay time ranges from 0s to 60s with
the resolution of 1ms. When the instrument is used in automatic test system, the
delay function will be useful.
Operation steps for setting delay function
Execute the following operations to set delay time.
1) Move the cursor to DELAY.
2) Use numeric keys to input the delay time. Press a numeric key, the following
unit soft keys will be displayed. Use them to replace [ENTER] and input delay
time.

sec
6.2.2 Bias
There are two modes for setting DC bias. The first one is using soft keys and the
other one is using numeric keys.
1) Move the cursor to DC BIAS, the following soft keys will be displayed.
(+)
Press this key to increase the output level of DC bias.
(-)
Press this key to decrease the output level of DC bias.
2) Use soft keys or numeric keys to select or set DC bias level. When using
numeric keys to input the bias level value, the available units (mV, V, μA, mA
and A) will be displayed in the soft key, which can be used to input unit and
data. When using [ENTER] to input the bias value, the default unit is V or A.
———————————————————————————————————————
Note: When you want to switch DC bias level between current and voltage, the
numeric keys and unit keys must be used.

When using transformer parameter auto sweep function to test inductance, the
instrument will automatically output the preset DC bias. When DC bias is allowed
to output, [DC BIAS] will light up.
6.2.3 MODE
Move the cursor to MODE, the soft key zone will display SEQ and STEP.
