3、 Detailed explanation of functional features

1. Diversity of signal input

-Supports multiple thermocouples: K, R, T, J, E, B, S, etc

-Compatible with various types of thermal resistors: Pt100, 350 Ω, 500 Ω, etc

-Can receive DC voltage (± 10mV~± 10V) and current signal (4~20mA, requiring an external 250 Ω resistor)

-Input impedance ≥ 10M Ω (voltage measurement) to ensure accurate signal measurement

2. Advantages of recording system

-High speed printing: The paper feed speed can be selected from a range of 0-1500mm/h (34 speeds) or 5-12000mm/h (41 speeds) to meet different recording density requirements

-Multi color recording: Use a 6-color disposable touch pen ribbon (red, green, purple, etc.) for easy differentiation of different measurement states

-Automatic time marking: Record the automatic printing time, scale value, and channel number on paper

-Anti interference design: Isolation technology is used between channels, with strong anti-interference ability (CMRR ≥ 140dB, NMRR ≥ 60dB)

3. Convenience of operation and maintenance

-5-key design operation panel to achieve standardized operation process

-Clear button functions: FEED (forced paper feeding), SET (setting), up and down arrows (parameter adjustment), ENTER (confirmation)

-Easy replacement of recording paper: Open the paper tray, align it with the drum tooth hole, and install it

-Quick ribbon replacement: disposable design, no need for ink replenishment

4. Alarm and control functions

-Each channel can independently set 4 levels of alarms (upper limit H1/H2, lower limit L1/L2)

-The alarm return difference can be adjusted (about 0.5%) to avoid frequent triggering

-Relay output during alarm, can be linked with external devices to achieve safety protection

4、 Working principle

RM1001C0000 adopts a combination of mechanical and electrical working methods:

1. The input signal (temperature, pressure, etc.) is amplified and filtered by the signal conditioning circuit

2. Convert analog signals into digital quantities through high-precision AD converters

3. The microprocessor processes data and controls the lateral displacement of the recording pen

4. Simultaneously drive the paper feeding mechanism to achieve longitudinal movement

5. The recording pen draws a curve proportional to the input signal on the recording paper

5、 Application scenarios

RM1001C0000 is widely used in the following fields due to its stability and reliability:

1. Industrial temperature monitoring: heat treatment furnaces, reaction vessels, drying equipment, etc

2. Environmental monitoring: Temperature and humidity records for pharmaceutical factory cleanrooms, food processing workshops, and warehouses

3. Energy industry: Temperature monitoring of power equipment, recording of boiler operation status

4. Laboratory research: Long term tracking of scientific research experimental data, performance evaluation of testing equipment

5. Medical equipment: Temperature records of medical instruments such as sterilizers and incubators

6、 Usage Description

1. Installation preparation

-Select a flat panel with a hole size of 144 × 144mm

-Insert the recorder from the rear and secure it with a fixing clip

-Connect the power supply and signal input to ensure good grounding

2. Installation of recording paper and ribbon

-Open the recording paper compartment door and place the recording paper facing upwards

-Align the paper hole with the drum teeth and pull the paper to the starting position

-Install the corresponding model ribbon (WPSR series) and ensure it is securely fastened

3. Basic operating procedures

```

Power on → Set parameters (range, paper feed speed, alarm value) → Start recording → Daily monitoring → Regularly replace recording paper

```

-Paper feed speed setting: Usually selected based on the frequency of measurement signal changes. For rapid signal changes, choose high speed (such as 500mm/h), and for slow changes, choose low speed (such as 10mm/h)

-Record interval: data points can be printed every 1-99 minutes for easy data reading

7、 Comparison with similar products

RM1001C0000 vs RM1002C0000 vs RM1006C0000：

-RM1001C0000: Single channel pen style, suitable for long-term monitoring of a single parameter, cost-effective

-RM1002C0000: Dual channel pen style, capable of recording two parameters simultaneously for easy comparison and analysis

-RM1006C0000: Six channel dot matrix (non pen), capable of monitoring six signals simultaneously, suitable for complex systems

Paper recorder vs paperless recorder:

-Advantages of paper: data is intuitive and visible, historical records can be accessed without the need for a power source, strong resistance to electromagnetic interference, and legally recognized original vouchers

-Applicable scenarios: Industrial environments that require long-term storage, legal traceability, or unstable power grids

8、 Selection and maintenance suggestions

Key points for purchasing:

-Confirm the type of measurement signal (thermocouple, thermistor, or voltage/current)

-Select the number of channels based on monitoring requirements (RM1001C0000 for a single channel)

-Considering environmental factors, choose products with IP65 protection level

-If remote monitoring is required, confirm whether the communication interface meets the requirements

Maintenance and upkeep:

-Regular replacement: recording paper (approximately 16 meters long, with usage time determined by paper speed) and ribbon

-Cleaning and maintenance: Clean the casing monthly to ensure good heat dissipation

-Long term disuse: unplug the power and store in a dry and dust-free environment
