STB6684/A Operation Manual
4.2.3 Setting nominal value
In tolerance mode, it is necessary to set the nominal value. In the display range, it can be set
to any value.
In sequential mode, the nominal value is not necessary but can be set.
Operational steps for setting nominal value:
1)
Move the cursor to NOM.
2)
Press numerical keys to input the nominal value. Units (pA, nA, µA, mA) or (kΩ, MΩ,
GΩ, TΩ, PΩ), corresponding to the parameter, will be displayed in the softkey zone.
You can select the desired unit to end inputting. When [ENTER] is used to finish
inputting, the default unit is the same as that input last time. When the *1 softkey is used
to input the nominal value, A or Ω can be selected as the default unit.
4.2.4 High and low limits
STB6684/A can set the limits for 4 bins. The test result is sorted to 5 bins at most (from BIN1
to BIN5). High and low limits can be set in HIGH and LOW zones from BIN1 to BIN5.
Operation steps for setting high and low limits:
1)
Set PARAM, NOM. and MODE.
2)
Move the cursor to TOOLS, press CLEAR TABLE to clear the current bin limits.
3)
Move the cursor to LOW of bin1. If you select tolerance mode, execute step 4 to step 5;
if you select sequential mode, execute step 6 to step 10.
4)
Use numerical keys to input the low limit value of Bin1, after inputting data, use (pA,
nA, µA, mA) or (kΩ, MΩ, GΩ, TΩ, PΩ) to replace [ENTER] to input the limit unit.
When use [ENTER] to end inputting, the default unit is the same as that input last
time.After inputting limit value of bin1, the low limit of bin1 is set as – (absolute limit),
high limit of bin1 is + (absolute limit).
————————————————————————————————————
NOTE: When the tolerance mode is selected as ABS TOLE, corresponding usable units
will be displayed in the softkey zone; when the tolerance mode is selected as % TOL, no
softkeys will be displayed and user can only use [ENTER] to confirm inputting.
————————————————————————————————————
5)
The cursor is jumped to LOW of bin2. Repeat step 4 until limit values of bin4 are input.
6)
Use numerical keys to input the low limit of bin1, after inputting data, use (pA, nA, µA,
