Compact light instrument, is intended for the measurement and the writing into the memory of the values of the temperature before different time intervals with the use of the built-in or external sensor.

• Large volume of internal storage, to 16000 elements of data.
• Possibility of connection based on PK on the means USB or RS-232 (option) and graphing regarding the obtained values.
• Possibility of the automatic writing of the measured values into the memory of instrument during the long time, through the established time intervals.
• Data remain before the memory of instrument, even when battery is discharged.
• The presence of the function of power of save (savings of energy), function makes it possible to increase the duration of record.

Specification

Model	3634-20
Characteristics	Registrar can measure and write instantaneous values based on the sensor, which is connected to it beside the memory. Sensors can have different time of response. This there can be the temperature sensors, pressure, humidity and so forth, necessarily only so that the signal going from the sensor on registrar would be direct current to 20 mA, therefore as registrar it was capable to measure only current signal DC to 20 mA.
Measured signal	Current DC, from 0 to 20 mA (1 channel)
Measured ranges	DC from 0 to 20 mA
Accuracy (is guaranteed at a temperature dist. of the medium: 23 ± 0.5 °C)	± 0.8% of chg of [velich]. ± 5 un. Temperature coefficient: 0.08%/of °C
Volume of internal storage and the record	To 16000 elements of data ([vyborok] of the results of measurements).
	Beginning of the record: with the pushing of knob or with the aid of the timer the intervals of the record: 2/5/10/15/20/30 seconds, 1/2/5/10/15/20/30/60 minutes.
Regimes of the record	-
Duration of the record	Approximately in 1.5 weeks the memory of instrument will be filled, with the interval of record 1 minute. With the switch oned function of power of save (savings of energy).
Interface	Infrared optical connection between the instrument and communication line bases 3911-20, 3912-20. The connection between communication line base 3911-20 and PK is achieved with the aid of RS-232. The connection between communication line base 3912-20 and PK is achieved with the aid of USB 1.1
