CONT CHEC
This function is used for setting the contact check of the instrument. As the unique contact check
function of TH2683A/TH2683B, this function can well identify the contact performance of
components for capacitance, cable and other capacitive materials and reduce the occurring of
error test. In addition, the contact check will not increase any measurement time.
When the CONT CHEC function is set as ON,
NO CONT
(NO CONTACT), not R or I will be displayed
on the screen if the instrument is in test mode and no capacitive material is detected.
When the CONT CHEC function is set as OFF, the instrument will test the value directly, not check
the capacitive material.
Steps for setting the CONT CHEC:
Touch the corresponding zone. The following items will be displayed in the soft key zone.
ON
It is used for setting the CONT CHEC as ON.
OFF
It is used for setting the CONT CHEC as OFF.
Touch the corresponding key in soft key zone to select the relevant function.
NOTE: The contact check function is useful when testing capacitive materials and the capacity is
larger than 100pF.

OPEN CLR
This function is used for operating open clear of the instrument.
Steps for setting the OPEN CLR:
Touch the corresponding zone. The following items will be displayed in the soft key zone.
ON
It is used for setting the OPEN CLR as ON. If the open clear is successful, the OPEN CLR state
changes to ON; if the open clear is failing, the OPEN CLR state keeps OFF.
OFF
It is used for setting the OPEN CLR as OFF.
Touch the corresponding key in soft key zone to select the relevant function.
NOTE:
1.
If the user operates the open clear successfully, the clear base used in the instrument
is the base obtained when operating this open clear; if the user operates the open clear
unsuccessfully or sets the OPEN CLR as OFF, the clear base used in the instrument is the
Factory Default.
2.
When operating open clear, the user must conform to the condition described in
Chapter One—“Environment”, pull out all the test lines in test terminals and heat the
instrument for more than 30 minutes, otherwise it may result in inaccurate clear base and
