Note
For TC measuring, cold junction temperature compensation in two ways:
①
Auto: is using the internal temperature measurement value as cold-
junction compensation;
②
Man: is manually setting cold-junction compensation value and refer
to"6 parameter settings."
4.8 Source Frequency Signals
1 Connect the terminals Figure 4.1.
2 Use the FUNCTION key on the SOURCE, when the output interface
is marked as Frequency (FREQ).
3 Use the RANGE key to select he range (Ran 0-1KHz) and (Ran 0-
5KHz) switch.
4 Use the Direction keys or numeric keys to set the output value.
Press the Zero key, return to the initial value is set to "0."
5. Measurement
Warning
Turn off the power supply to the object to be tested before connecting it to
the instrument. It is extremely dangerous to connect and disconnect
measurement lead cables while power is being supplied to the object.
• It is extremely dangerous to incorrectly connect the voltage input terminal
Hand the current input terminal mA. Make sure that the measurement
function (FUNCTION) selection and terminal connections are correct. An
incorrect connection may not only cause damage to the circuit or device
under test and the instrument, but also result in injury to the operator.
• The maximum allowable applied voltage for the grounding of all
input/output terminals is 30 Vpeak. Be sure not to exceed this voltage
because doing so may not only cause damage to the instrument, but also
result in injury to the operator.
