automatically turn off if no operation has been made
within 15 minutes.
The Users can set by themselves to choose whether
using this function or not (See Section Six).
Section Five-Output of the Meter
The meter generates DC current or simulate
resistance set by the Users from the corresponding
output terminals (OUTPUT).
Caution

6. Automatic compensation of cold junctions
When calibrating meter with temperature cold
junction compensation directly, press 〔RJ-ON〕key to
start the automatic compensation function of cold
junctions of this meter, and it will output the necessary
temperature thermoelectric force, and display „RJ-ON‟.
(See Section Seven for the accuracy of cold junction
compensation), and :
Output thermoelectric force = the corresponding
thermoelectric force of set temperature –the
corresponding thermoelectric force of room temperature
* The Users need to wait for 2 seconds when
starting the interior cold junction compensation of
the meter and the meter will make automatic
compensation every 10 seconds
* When the operation ambient temperature change,
the Users need to wait until the interior
compensation sensor stabilizes (about 10 minutes)
and then use
* If the Users do not use the automatic compensation
function of this meter, press the〔RJ-ON〕key and
the symbol‘RJ-ON’will not display any more

0000.0C(other graduation).
8. Press〔℃/℉〕key , select Centigrade or Fahrenheit
unit.
(3) Resistance or thermal resistance(RTD)simulate
output Note
·Resistance simulate：The meter generates a simulate
resistance value ranging from 400to 4000
from the output terminal (RTD/). The output
method for simulate resistance is that the
meter outputs corresponding voltage “Vx
“according to incentive current “Ix” generated
by the calibrated meter, and for the R(set
resistance) equals to Vx(output
voltage)/lx(incentive current), thus the
calibrated body should supply a simulate
current to this meter. For realizing the
correct simulate output of 400Ω, the incentive
current should be within ±0.5～±3mA range;
for simulate output of 4000Ω, the incentive
current should be within ±0.05～±0.3mA
range; Note
·Resistance simulate：when the output resistance is
4-wired for calibration, the error generated by
the resistance (approximately 0.1) of test
lead should be considered if the Users employ
two wires connection method; The meter may
generate incorrect resistance value if the
capacity between the output terminals and the
measured meter is higher than 0.1 uf.
Figure 5-2
1. Insert the testing probe into the jack of the meter‟s
output terminal (RTD/), and connect the other end
with input terminal of the Users‟ meter, see Figure
5-2: (the dedicated testing probe supplied by the
meter can be connected as three-wired or
four-wired output as required by the Users)
