CL3152A Calibration Procedure | Omega CL3512A specs

Display: 3½ digit liquid crystal display (LCD) with a maxim um reading of1999.

Polarity: Automatic, positive implied, negative polarity indication.

Overrange: -OL is displayed.

Zero: Automatic.

Low battery indication: The “” is displayed when the battery voltage drops below the operating level.

Measurement rate: 1 times/second.

Accuracy: Stated accuracy at 23°C±5°C, <75% R.H.

Dimensions: 195mm(H) x 92mm(W) x 53mm(D).

Weight: approx. 9 oz. (250g) including battery.

Input Connector: Accepts standard miniature thermocouple connectors (flat blades spaced 7.9mm, center to center SMP type).

Battery Life: 100 hours typical with carbon zinc battery.

Auto power off: The meter key switch inactive for more than 90 minutes.

Temperature Coefficient: 0.1 times the applicable accuracy specification per

°C from 0°C to 18°C and 28°C to 50°C (32°F to 64°F and 82°F to 122°F). Input Protection: 24V dc or 24V ac rms maximum input voltage on any

combination of input pins.

Maximum Differential Common Mode Voltage (Maximum Voltage betweenT1 and T2 during measurement): 1volt.

Note: The following calibration procedure should be performed only by qualified technicians who have access to the items as following items:

Equipment: Thermocouple calibrator had better 10 times greater than the measured meter.

1.Short CAL jumper and turn on the meter to INPUT range.

2.Press “ ” key display was showed 35°C / T1/ SET / K.

3.Input 35°C / K-type to the T1, then press “ ” key and wait for the display was showed 1300°C / T1 / SET / K.

4.Input 1300°C / K-type to the T1, then press “ ” key and wait for the display was showed 0°C / T1 / SET / K.

5.Input 0°C/K-type to the T1, then press “ ” key and wait for the display

was showed “-OL” then press “ ” key and wait for the display was 35°C / T2 / SET / K.

6.Input 35°C / K-type to the T2, then press “ ” key and wait for the display was showed 1300°C / T2 / SET / K.

7.Input 1300°C / K-type to the T2, then press “ ” key and wait for the display was showed Out / K / °C / SET / T2.

8.Knob being with clockwise rotation 2 range and two knobs of lower left corner are set to the position of the middle (horizontal).

9.Press “ ” key and wait for the meter auto power off then remove jumper.

10.The calibration was completed.
