- Function Overview:
- Working environment: temperature -10~60 ℃; Humidity ≤ 90% RH
The input adopts a precise and stable digital calibration system, supporting multiple thermocouple and thermistor specifications, with a maximum resolution of 0.1 ℃.
The operation method of humanized design is easy to learn and use.
The anti-interference performance meets the requirements of electromagnetic compatibility (EMC) under harsh industrial conditions.
This instrument adopts maintenance free technology of automatic zero adjustment and digital calibration. If it exceeds the tolerance during metrological verification, it can be corrected by parameters
By default, it comes with four sets of relay alarms and can independently set alarm values.
- Input signal:
- Choose one of the following signals, fixed at the factory:
CU50(-50.0~150.0)、PT100(-199.9~600.0)、K(-50.0~1300)、 - E(-50.0~800.0)、 J(-50.0~999.9)、T(-50.0~400.0)、
- 0-10mA、4-20mA、0-10V、1-5V、NTC
- Control output:
- By default, it comes with four alarm relays and can be controlled in a positional manner (upper and lower limit control).
- Alarm output:
- Default with four-way alarm relay (special instructions required): '0' has no alarm; '1' upper limit alarm; '2' lower limit alarm;
- Appearance size:
- Length x Width x Depth (mm) A: 96 x 96 x 75 x 92 x 92;
D:72×72×75 68×68; E:48×96×75 44×92; F:96×48×75 92×44;

S: 80 x 160 x 85 x 76 x 156.

Sensor error correction |
| 11 | When the measurement sensor causes errors, this value can be used to correct them | DP | decimal place When the instrument is used for voltage or current input, its display upper limit, display lower limit, decimal point position, and unit can be freely set by the manufacturer or user. When dp=0, the decimal point will not be displayed in units, and when dp=1-3, the decimal point will be displayed in tens, hundreds, and thousands, respectively. |
| 12 | P-SH | Display upper limit | |
| 13 | When the instrument is used for voltage and current input, the digital display shows the upper and lower limit set values (this menu is not displayed for inputs other than voltage and current) | The user can independently set the range of instrument digital display. | P-SL Display lower limit |
| 14 | G-SH | Light column display upper limit | |

The upper and lower limits of the instrument light column display determine the display range of the light column. |
The display range is determined by P-SH P-SL |

PF |
filter coefficient |
17 |
For the first-order lag filtering coefficient of the instrument, the larger its value, the stronger its resistance to instantaneous interference, but the response speed lags behind. Its value should be relatively small for pressure and flow control, and relatively large for temperature and liquid level control. |
