How to restore your to its original specification after it has suffered the ravages of time and temperature.
Programs for 2-wire resistance in F4. When changing polarity during the checks; if leads are reversed it will be necessary to allow time for thermal effects to stabiuze in the reversed connection before proceeding with the check. Using the general sequence; At operation 3: Use Calculations A and C if the was last calibrated by Datron. The I-command and the WI command must not be sent in the same siring.
The key LED indicates the true connection: Operation of tlie Safety trip, buzzer and. V lt Record in 4Vi digits resolution e. When sending general messages, the controller makes all bus devices interpret any DlO-iinc data as configuration or data- flow commands, adtron holding the ATN line true.
The updated correction factors are applied in the normal RUN mode.

Recall from a Different Memory To switch to a different stored frequency: A second press cancels the function. Datro the fuse extractor to the normal position. Veiy selective bandpass notch filtering is required; this is usually achieved by phase-locking the measurement circuitry to dstron signal, as performed by a selective signal level meter. Details of tlie High Voltage selection procedu,re are given in Section 4.
The characters are appropriate to the programmed state of the 47 X.

Programs for 4-wire resistance in F4. Uncertainty and Traceability 7,33 6. The IFC line is used at the discretion of the controller, to clear any activity off the bus. The purpose of this explanation is to describe dayron effects of these codes on the output string format.
Ranging down occurs at. Analog Output On by an Output Enable message.
Linearity error — the slope of the line varies. It is assumed that users will pos. Contact factory for detaiis. This section deals with user-verifi cation of the performance to specification.
On n ranges, only the overrange f f are operative. COOOmV 99, 0. Sending the I command will store the subsequent 1 6 character string in dahron 7.
DATRON MULTI-FUNCTION METER CALIBRATOR –
Slide the window to the left to reveal the fuse and PC selector board. The value displayed depends on the selection of Local 2-wire or Remote 4- wire Sense, and should be recalibrated in the correct Sense mode See Datgon 8. After selecting fl, Remote Sense must be cancelled for 2-wire operation. SET can also be used as a means of compensating for known errors in the Measurement System.
The ratio ; Total Lead Resistance Load Resistance gives the approximate error for 2-wire connection at low frequencies.
Test Instructions These instruments can produce or measure lethal voltages at their terminals. Any combination of these two FAIL messages can appear in sequence, replacing the running message.
This is deariv not a practical proposition following delivery. You acknowledge that all comments express the views and opinions of the original author and not those of the administrator. A For calibration at any value, this routine may be used as printed. Routine adjustment of tite resistor is not necessary.
Continue increasing sensitivity and backing off until the null lies between two consecutive values of the OUTPUT display le as t- s ignific ant digit Ensure that the null obtained is stable. Remove any zero offset. Where possible, the specification and Datron calibration uncertainties are given in a form suitable for calculation see Report Sheet RS2Where this IS not possible titey can be assembled from the specifications in Section 6, and in some cases can be more easily obtained using Spec Mode Report Sheet RS3 has columns for this purpose.
Inputs The microprocessor controls tlie output in response eatron three main inputs: Offset or Error Mode is selected:
