18. ADJUSTMENT 18.1 Adjustment of Measured Values

■ Adjustment

Adjustment comprises four kinds shown below. (1), (3) and (4) have already been adjusted. However, it is

recommended for maintaining the measuring and printing accuracy to adjust them once a year.

Calibration Details

Reference

(1) Measured values adjustment Adjustment to keep the measured value against input within

the accuracy ratings. Sec.18.1

(2) Shift programming of

measured value Programming to shift a measured value Sec.18.2

(3) Adjustment of printing position Adjustment to set the printing range to the zero and span lines

on the chart Sec.18.3

(4) Adjustment for time -axis

synchronization of pens Adjustment of the gaps between pens for the time-axis

synchronization Sec.18.4

1 Adjustment of measured values

It is recommended for maintaining measuring and

printing accuracy to adjust them once a year.

(1) Execute the adjustment for each channel.

(2) Execute the adjustment under the reference

condition. (See the right table.)

Items Reference conditions

Ambient temperature 23 ±2°C

Ambient humidity 55 ±10%RH

Power voltage 100 ±1VAC

Power supply

frequency 50 or 60 ±0.5Hz

2 Preparation

1) Preparation of tools

Input types

Tools DC voltage Thermocouple Resistance

thermometer

Remarks

DC standard

voltage/current generator ○ ○

Accuracy: Should be better than ±0.05%.

Reference junction

compensator ○ 0°C ±0.2°C or less

Thermocouple for test ○ Same type of thermocouple as input type

Standard variable resistor ○ Accuracy: Should be better than ±0.05%.

3-core copper wire ○ Same resistance for each 3 cores

2) Connection

Connections depend upon the input types. See the next page.

3) Before starting adjustment

(1) After the connection, mount the terminal board cover and turn on the power supply.

(2) Before starting adjustments, warm up your recorder for at least 30 minutes until it becomes stable. (It is

recommended to warm it up for at least one hour if possible.)

Check and adjustments of the measured values need meticulous work in addition to the standard tools and

reference conditions.

If you need checks or adjustments of the measured values, please consult your nearest CHINO’s agent.
