Device is P-603 (P603, P 603)
1.1. P-603 device is designed for:
a) The accounts of a randomly distributed in time or a periodic sequence of pulses for the four independent from each other by channels from the four test signal sources simultaneously;
b) measuring the frequency or the following account of the number N of events from the three sources of pulsed signals simultaneously on three channels with the possibility of counting the preset one of the five fixed values of N;
c) the account number matched in time of pulses from the two sources of signals on one channel of a countable;
d) the operations of summation and continuous account.
1.2. Instruments P-603 suitable for use in temporary shelters, tents, trailers and bodies in a car:
ambient temperature of 243-323 ° K (from -30 ° C to +50 ° C), relative humidity up to 308 ° at a temperature of K (35 ° C), low atmospheric pressure up to 61 300 Pa (460 mm Hg).
2.1.The instrument produces a P-603 due to the repetition frequency and measurement of pulse signals a positive or negative polarity, the length sensitivity of 0.2 - 10 ms, an amplitude of 2-50 V with a signal-to-noise ratio of 4:1 and a resolution of 1.6 microseconds.The range of measurement repetition frequency of 40 Hz to 500 kHz, a range of accounts up to 500 kHz.
2. 2.The input impedance of each channel unit is not less than 1 ohm with parallel capacitance to 50 pF.
2.3The relative error in measuring the pulse repetition rate does not exceed the value determined by the formula
δ = ± (δ 0 + 1 / (f ∙ t))
where δ 0 - frequency error of its own crystal oscillator or an external standard frequency oscillator used in place of its own crystal oscillator frequency;
δ 0 = ± 1 ∙ 10 -4 - error rate of its own crystal oscillator;
1 / (f ∙ t) - the error due to mismatch of the measured phase signal and the pulse determines the start and end time of measurement;
f - the measured frequency (Hz);
t - time of measurement (s).
2.4The maximum error in the account depending on the volume the pulse repetition frequency at 100 kHz does not exceed the values given in Table 1:

The maximum error in the account
2.5. The maximum amount of each invoice elektronnoschetnogo channel device is June 10.
2.6. The device P-603 provides a direct readout of the results of measurements of the pulse repetition frequency in hertz.
2.7. The instrument produces a count of the number of pulses in the intervals of time kvartsovannye 1 ∙ 10 -3 C 1 ∙ 10 -2 C 1 -1 C ∙ 10, 1C, 10s.
2.8. The device has a manual (the buttons) and an external reset, start and stop counting device, and automatic shutdown in dependence on the accounts or time of measurement.
Parameters of external control signals: reset voltage of 10V ± 10% positive or negative polarity, start and stop the momentum of positive polarity, an amplitude of 8 V ± 15% and a duration of 1.2 ms.
2.9. The device supports the work of the external clock input signals with the parameters in accordance with clause 2.1.
2.10The device provides kvartsovannye frequency of 100 kHz or 500 with respect to accuracy better than ± 1 ∙ 10 -4.
2.11.The device produces signals of large-scale relief and stop:
RESET - voltage minus 11V ± 10%;
START - rectangular negative pulse amplitude of at least 8V;
STOP - pulse of negative polarity amplitude of at least 8V.
2.12.The device has a mode of self-control, allowing the device to verify proper operation prior to measurement.
2.13The device is supplied from the AC voltage 115/220B ± 5%, frequency 380-525Gts.
Power consumption 200VA.
2.14.Warm-up time the unit is not more than 5 minutes.
2.15.Guaranteed lifetime of the device for three years, two of them of so close a year of operation and transportation and storage.
2.16.Weight of the device with the packing box is not more than 34 kg. Weight of device without packing box is not more than 20 kg.
2.17.Overall dimensions of 583x397x319 mm packing box. Dimensions without packing box 502x338x271, 5 mm.
2.18.The device allows continuous operation for 16 hours.
