(2) REL function
Pre-set a reference value, then every value must minus the reference
value before displaying on the panel for the compare judgment.
(3) Single range
There is only a single range for the temperature measurement.
6-3. Temperature Compensation Measurement
(1) Temperature compensation measurement mode
1) The adequate resistance value of the DUT can be calculated through
the environment temperature, the setting coefficient of temperature
of the DUT, and the require observation temperature.
2) Press [SHIFT] and [TEMP] in sequence getting into main function
selection mode.
3) Press [▲] or [▼] can switch over 3 kinds of functions of “ohm”, “℃”, and
“TC” on the panel.
4) Select “TC” and press [ENTER] getting into temperature compensation
measurement mode.
5) The up limit percentage area display the observation temperature and the
setting coefficient of temperature will be displayed on the normal value
displayed area.
6) Use [▲] or [▼], [ ] or [ ] to set the require observation temperature
and the coefficient of temperature, then press [ENTER] to confirm the
setting or press [SHIFT] to clear the setting.
(2) Range selection
Use [▲] or [▼] to switch over the range or set [AUTO/MAN] to auto range

6-4. General Function
(1) Converted speed selection
1) Press [SHIFT] and [SPEED] in sequence to switch over the
converted speed.
2) Low converted speed: 7 times/second, full scales: 30000.
3) High converted speed: 30 times/second, full scale: 3000.
4) The converted speed function can be applied on the measurement of
resistance, temperature, and temperature compensation.
(2) Auto range function
1) Press [AUTO/MAN] to switch over auto range or manual range.
2) Under the Compare mode, switch over the range will annulled the
previous setting of % or REL function.
3) The temperature measurement only has a single range.
4) Under external trigger mode, Auto range function is disabled.
(3) Trigger function
1) Press [MANUAL TRIG] getting into external trigger mode.
2) Each time when the [MANUAL TRIG] button is pressed, the EXT
LED will be flashing once and the panel value will be updated again.
Press [SHIFT] and [INT] in sequence to leave Trig mode.
