4. Click or tap to enable or disable the relative operation function.
When enabled, the displayed reading value is the result obtained by subtracting
the set relative value from the actual measurement value. For the relative value
setting methods, refer to descriptions in "
Math Operation
".
5. Read the measured value
The period measurement is measured at a fixed "slow" rate with a 5.5-digit
display. Therefore, the reading rate cannot be adjusted during measurement
results reading.
6. Hold the reading data
Press
to run and hold the reading data displayed on the screen.
5.3.10 Any Sensor Measurement
By using any sensor measurement, you can connect Pressure Sensor, Flux Sensor or
Temperature Sensor easily. This function enables you to easily convert a measured
physical quantity (such as pressure, flow rate and temperature) into a quantity that
can be easily measured (such as voltage, current or resistance). By pre-inputting a
response curve, the multimeter converts and amends the data according to the
internal arithmetic and displays the physical quantity measured on the screen. Users
can edit and modify the display unit of the measured physical quantity at will.
The multimeter supports DCV, DCI, Freq, 2WR, 4WR, and temperature sensor
measurement (TC, RTD, Therm). Meanwhile, there are 10 groups of basic Sensor
preset within the instrument.
Connection
Different sensors have different connection methods. For the Voltage Sensor,
Resistance Sensor, Thermocouple Sensor and Frequency Sensor, please connect the
red lead to terminal Input-HI and black lead to terminal Input-LO, as shown in the
figure below.
