Notes:
1) Based on ITS-90 (ITS: The International Temperature Scale ); the
environmental condition: (23±5)℃, ≤85%RH; exclusive of sensor errors.
2) The thermal resistance and thermocouple’s measurement range and tolerance
shown in other units (℉and K) are equivalent to the above table.
3) The Fahrenheit degree (℉) is not the legal measurement unit in the P.R.C, so
Fahrenheit degree (℉) cannot be used as temperature measurement unit
except for special need.
4) When environmental condition not in (23±5) ℃, means (0~18) ℃and
(28~50) ℃, tolerance will increase 0.01Δ/℃

1. Wiring for RTD type:
The 4-wire connection is adopted, which is shown as F1 in the above drawing.
Two wires which in red and white color are connected to one end of the RTD, and
two wires which in black and green color are connected to the other end of the
RTD.
Special Notes: the 4-wire connection plug cannot be used as USB interface
purpose. It cannot be plugged into any USB sockets of computers or other devices
so as to avoid damage

2. Wiring with the interior reference end compensation method (INT) is
adopted for thermocouples:
The same thermoelectric characteristics should be ensured for connection from the
thermocouple measurement end to the plug, that’s to say, the compensation wires
and plugs should be used as the same type as the “tyPE”, the extension type is
preferable. See F2 in the above drawing.
3. Wiring with the manual reference end compensation mode (MAN) or the
external reference end compensation mode (EXT):
The thermocouple to the constant temperature oven is connected by compensation
wires; The constant temperature oven to the instrument is connected by pure
copper wires and plugs. With regard to the external compensation mode (EXT),
a four-wire Pt100 platinum resistance is required to be inserted into the
constant temperature oven, and a four-wire plug is required to be connected to
the RTD socket of the instrument, which is shown as F3 in the above drawing.
Note 1:
If thermocouple plug and RTD plug are connected to sensor in the same
time, insulation between the sensors should be ensured, or the
measurement results will be affected.
Note 2:
If any signals exceeding 5V are input, the instrument will be damaged.

Keys are divided into three types including the short keys, long keys and key
combinations. Long keys or key combinations (keys should be pressed and hold
for 2 seconds) are used to realize the functions of Set, Cancel, RJ or Cal, and
short keys are used to realize other functions.
(1) Power Key: Power switch, the automatic shut-off function can be realized
when the menu parameter AutoFF is not equal to 0. That’s to say, automatic
shut-off can be realized when no key-press time is larger than or equal to the time
set by AutoFF (unit: minute), and automatic shut-off is canceled when AutoFF is
equal to 0.
(2) Backlight Key: Backlight switch. The absolute value of the menu parameter
Auto.b.L is the backlight’s automatic shut-off time (second), and the backlight’s
automatic shut-off function is canceled in case of Auto.b.L=0. The positive and
negative signs of Auto.b.L indicate that if the buzzer sound for key-press and alarm
exceeding the lower/upper limit is allowed or not: buzzer sound is allowed when
