Abstract
The utility model provides a calibration device with a calibration box. The calibration box comprises a box body. Two 300W and 5-omega type resistors are connected in parallel in the box body. The two resistors connected in parallel are fixed into the box body through screws. Red and black leads are led out of the two ends of the resistors connected in parallel. The red and black leads are configured to extend out of the box body through insulating holes in the box body. The calibration device comprises to-be-calibrated equipment, standard equipment and the above calibration box. The power interface of the to-be-calibrated equipment is connected with the test hole of the standard equipment through a cable. The red joint of the cable is connected with the anode test hole of the standard equipment, and the black joint of the cable is connected with the black lead of the calibration box. The cathode test hole of the standard equipment is connected with the red lead of the calibration box through a lead. Due to the adoption of the above calibration device, both the calibration accuracy and the calibration efficiency are improved. Meanwhile, the calibration requirements of various output DC voltages and various output DC currents can be met at the same time.
Description
Technical field
The utility model relates to a kind of calibrating installation of applying check box, belongs to collimation technique field.
Background technology
In Radio Measurements calibration industry, what in calibration process, some equipment adopted the is mutatis mutandis standard device of contact pin or jack type p-wire high-ranking officers be calibrated equipment connection and calibrate.In calibration process, because being calibrated the reserved calibration interface of equipment, majority is used for being connected with computing machine, and the interface of our selected measurement standard equipment in calibration process is often different from the interface of computing machine, therefore in calibration process, just there are some problems, as with contact pin by standard device with being calibrated equipment connection when, the spacing of instrument connection and instrument connection is very little, along with output voltage strengthens, if tester is slightly careless, just can cause short circuit, short circuit very easily causes casualties and complete machine damages, make simultaneously calibration personnel and electrical equipment safety cannot to ensure.
Utility model content
For above deficiency, the purpose of this utility model be to provide a kind of can be calibrated that equipment coupling is connected calibrating installation.
The technical solution of the utility model: a kind of calibrating installation of applying check box, described check box comprises box body, be connected to two 300W in box body inside, the parallel resistance of 5 Ω, this parallel resistance is fixed by screws on box body, draw respectively red wire and unlicensed tour guide's line from the two ends of parallel resistance, red wire and unlicensed tour guide's line reach outside box body via insulated hole on box body, described calibrating installation comprises the equipment of being calibrated, standard device and check box, wherein be calibrated between the power interface of equipment and the instrument connection of standard device and connect by cable, the red joint of cable is connected with the anodal instrument connection of standard device, the black joint of cable is connected with unlicensed tour guide's line of check box, the negative pole instrument connection of standard device is connected with the red wire of check box by wire.
The beneficial effects of the utility model: calibrate, repair various detectors by the check box by the design, ensured that measurement standard is connected with the secure match that is calibrated equipment; The calibrating installation that adopts above-mentioned check box to form, has not only improved calibration accuracy and calibration efficiency, and can meet the calibration of various output dc voltages and output DC current simultaneously, has shortened greatly the alignment time in addition, has improved work efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of check box.
Fig. 2 is the embodiment of calibrating installation.
Embodiment
As depicted in figs. 1 and 2, a kind of calibrating installation of applying check box, described check box comprises box body, be connected to two 300W in box body inside, the parallel resistance of 5 Ω, this parallel resistance is fixed by screws on box body, draw respectively red wire and unlicensed tour guide's line from the two ends of parallel resistance, red wire and unlicensed tour guide's line reach outside box body via insulated hole on box body, described calibrating installation comprises the equipment of being calibrated, standard device and check box, wherein be calibrated between the power interface of equipment and the instrument connection of standard device and connect by cable, the red joint of cable is connected with the anodal instrument connection of standard device, the black joint of cable is connected with unlicensed tour guide's line of check box, the negative pole instrument connection of standard device is connected with the red wire of check box by wire.
When calibration, the power switch of standard amperemeters is placed in to open mode, " on-off " switch is placed in the state of " leading to ", then adjusts the DC current on standard amperemeters, reads the DC current values of the equipment of being calibrated on standard amperemeters.
