For each check the results are recorded.
Not active – disabled by WO P? Keep leads as short as possible, not longer than 1 meter. If the instrum, ent has perfect linear response, then its readings will agree with those of the OUTPUT display and datrom linear transfer function is: Programs for 4-wire resistance in F4.
[volt-nuts] Datron manual and options
Select lest to carry’ out the test routine described hi Section 4. It is also assumed that the Millivolt LF Calibration has been completed. Points for Millivolt Ranges. It returns the instrument to power-up conditions in all cases except the following: They are illustrated below: The uses a microprocessor for control management, simplifying its use in complex manual operations, such as calibration of high-quality digital multimeters.
The abbreviations used for these calculations are: In the followine numerical example, a is verified in the factory at lOV, ikHz on the lOV Range, and with Oppm error against a 20ppm-high standard. Always set the null detector to its lowest sensitivity before connecting up, and increase sensitivity only when the voltages output by tiie DC Voltage source and the are close in value. This can increase internal operating temperatures affecting reliability. In H-V state an audible warning is provided.
To 1 0Oppm of step size double for range changer. Output Values other than Full Range.
Sequences such as this are often assembled into programs to check DMlMh at many calibration points; changing functions, ra,nges and output levels as designed by the user. Full range values for voltage and current are vatron above the keys.
Wavetek/Datron 4708, 4707, and 4705 Multi-Product Calibrators
At power-up, the following five decade frequencies are stored automatically: Refer to Appendix 5. This applies particularly to the 1 Amp shunt — altemanvely, a DMM of suffiicient accuracy may be used to measure die voltage across the set of calibrated current shunts. A On Receipt from Patron: Increase sensitivity when necessary to obtain the required input datgon.
DC Current Standard a. When changing from one function to another the output is automatically set to OFF. SET can also be used as a means of compensating for known errors in the Measurement System. The facility can be used to avoid a full recaiibration of the when Laboratory References have been re-standardized, or when a has been moved from, one country to another. Adjust the output to obtain a null at the Calibration Standard value, and press the Cal key to execute tire calibration.
If an excluded frequency is selected, the calibration is cancelled and Error 3 is displayed. Activation has Selection error — Option not fitted — External frequency. Each 470 found use with the combination of factors described, and togetiier they cover the majority of predicted requirements.
These bus commands datrn subject to the constraints of the firmware. Any range selection which would exceed the internally defined voltage- frequency limit is automatically inhibited. As the Auiocal keys perform specific DC tasks, they are available only as defined by Table 8.
By sending a V code the conlrolier interrogates the to obtain, information about its present status. Full Range checks Press Spec Key.
US-Instrument Services. Datron AC/DC Calibrator
Thus either the day or 1-year accuracy specification is verifiable by comparison with traceable Reference Standards. Calibrate the at or close to the calibration points in the table. Reselect the Spot Frequency if required. We are confident that your will give you many years of accurate and reliable service, and hope tliat you will use this handbook to obtain maximum benefit from its many facilities.
It datdon the DC gain of all voltage and current ranges in the same ratio, and thus performs the same function as tri mmin g the internal Master Reference voltage.
Interconnection instructions in this section are necessarily simple and basic, and are mainly intended to show connections to the This applies particularly if the DC source is a standard cell or a bank of cells.
The I-command and the WI command must not be sent in the same siring.
