【 4.6 】 mV Millivolt Signal
【 Mode 】
: The millivolt signal is divided into three modes: 110mV, thermocouple, WR
thermocouple, in the main interface.When 【 FN 】 is white, press 【 IN/OUT 】 to switch
【 Type 】
: Select the type of thermocouple TC-S, B, E, K, R, J, T, N
【 WR Type 】
: Select the type of WR thermocouple WRE25, WRE26
【 Temperature Unit 】
: Set to Celsius or Fahrenheit
【 Cold Junction Setting 】
: Select the temperature detected by the meter or the
user-defined temperature
【 Cold End Temperature 】
: Customized cold end temperature value
【 4.7 】 24V Loop Detection
Select the 24V label left and right in the OUT signal type interface to enter this
function state.In this state, displays the output 24V loop current on the main
interface.Unlimited input signal detection type
（1）Loop 1
: After starting the output, 24V voltage is output between the (OUT) port
and (COM) port, and the loop current is detected at the same time, and the current
is displayed in the "output 24V loop" area.This function can be used to test, for
example, pneumatic control valves or two-wire transmitters, supply them with 24V
power supply and detect current
（2）Loop 2
: After activating the independent 24V power supply.The (IN-) port
outputs 24V voltage between the (24V) port and the (COM) port.It does not affect
the detection type of the input signal by the (IN+) port.In this case, select mA for the
input signal type.Then the (IN-) port can be combined with the (IN+) port to form a
24V output,And at the same time detect the current loop.The function is similar to
the circuit one
（3）
Port (IN-) can be switched to independent 24V power supply function.It outputs
a single DC24V voltage, which is the (24V) port at this time.(24V) port used with
(IN+) to test two-wire transmitters

Notice!
①The difference between 24V loop detection and standalone 24V is:24V
loop detection output signal port to measure feedback current.
②Independent 24V port and output port can form 24V power supply,It
can also be combined with the input (+) to form a transmitter to supply
power and measure the feedback current of the transmitter
displayed in the original quantity position.For output, the cycle is displayed at the
original engineering position, and the unit is milliseconds.When the main interface
【 FN 】 is white, press 【 OUT 】 to switch between cycle and quantitative values, which
are distinguished by cursors.
The period value can be modified during quantitative output.In this mode, when the
cursor disappears after the output is turned on, the backlight of the up, down, left,
and right keys will turn blue.The function of the up, down, left, and right buttons will
also change, that is, the up is a single pulse sent.Down is program stop and reset, left
is no function, right is start/pause
