◼
MEAS
When the reference component is connected to the test terminal, you should
press
MEAS
. Then JK2830 will test the reference component and the test
result will be automatically input as the value of
REF B
.
4)
Use MEAS or numeric keys to input the reference value of the secondary
parameter. If the reference values of primary and secondary parameters have
been set in steps 2), you can skip this step.
5)
Move the cursor to the
DEV A
zone, the following soft keys will be displayed:
◼
OFF
◼
ΔABS
◼
Δ%
6)
Use above soft keys to set the deviation mode of the primary parameter.
7)
Move the cursor to the
DEV B
zone, the following soft keys will be displayed.
◼
OFF
◼
ΔABS
◼
Δ%
8)
Use above soft keys to set the deviation mode of the secondary parameter.

DC bias
JK2830 provides internal DC bias voltage from -5V to +5V.
Operation steps for setting DC bias:
JK2830 provides two methods to set the DC bias. The first one is to use soft keys,
while the second one is to input data by numeric keys.
1)
Move the cursor to
DC BIAS
, the following soft keys will be displayed.
◼
↑
(+) and
↑
(++)
This soft key is used to increase the output level of DC bias.
◼
↓
(-) and
↓
(--)
This soft keys is used to decrease the output level of DC bias.
2)
Soft or numeric keys can be used to select or set the DC bias source. When
numeric soft keys are used to input the desired bias level, the available units
((mV, V, µA, mA and A) will be displayed in the soft key zone. Users can use
these soft keys to input unit or data. When [ENTER] is used to terminate the
input of bias value, the default unit is V or A.
———————————————————————————————————————
NOTE: When you need to switch the DC bias level between current and
voltage, numeric keys and unit soft keys must be used.

Press the [BIAS] key on the front panel to allow the output of DC bias. When DC
bias is permitted to output, the [BIAS] key will be lighted.
