A 4-wire sense connection will reduce inaccuracies due to differences in the output impedances of the DC voltage source and the Resistance — a set of standard resistors covering ion to looMn, The ion to lOkn should be 4-wire type. Four points datfon important: Search the history of over billion web pages on the Internet.
DATRON 4700 MULTI-FUNCTION METER CALIBRATOR
Output datorn Display Control Each vertical pair of tit keys is assigned to the display digit above it. Keep leads as short as possible, not longer than i meter-twisted pair is preferable. Alternative methods, with tlie required equipment, are described in appendices. Before attempting any verification ensure the toliowmg steps are carried out.

The specification is in Section 6. If Option 20 is fitted, it is also calibrated to nominal values in DC Current, and to actual values in Resistance.
Offset cannot be selected or deselected when the is already in Error Mode. In manual operation the user who is exposed to danger from high voltages also has direct control of the output, but it is not possible to give the same degree of bufltun protection to exposed users when the instrument is under remote program control.

When changing to H function, the is datrob forced into Remote Sense for 4-wire operation. Max Guard to Ground voltage of V rms 2.
The Mode display presents the compensation ratio directly. The millivolt range is then verified at th,is standardized value by DVM measurement. EOl can be used even if both Cr and Lf are suppressed. CiiiTent and connect the appropriate shunt. This can increase internal operating temperatures affecting reliability. RANGE key value is tiom.
For 4-wire connections in Remote Sense Fig. Avoid making connections through Nickel, Tin, Brass and Aluminium. Remote Sense is available as follows: CAUTION When choosing a set of current shunts ensure that their power dissipation ratings are sufficient 7400 avoid permanent degradation from the self-healing effects of the current being checked. CAUTION Assistance is required to fit the into the cabinet Lift the into position in the cabinet, locate the tongues in the slides, and carefully slide backwards until the front ears butt up against tlie 7400 front Secure the front ears to the cabinet Also clear ventilation for fan cooling to operate properly.
Display and Key Checks If the Test Key is re-pressed before pressing any other key, a visual sequence tests the front panel: This allows two correction values to be stored for each output range. LED Check sequence commences: The must be already programmed to prepare data, DABi Data bytes sent by currently-enabled talicers to all currently-enabled listeners, DABu UNT Disables the talker on receipt of the last character. Option 90 permits the instrument to be mounted in a standard 19 inch cabinet Remove the two rear spacers from the case sides by releasing six screws.
However, available thermal transfer standards are not suitable for direct verification of the millivolt ranges, because their transfer elements are insufficiently sensitive.
Use the general sequence; At operation 3 ; Select Daatron. Section Contents The section is divided so as to group certain types of mformatioo together. Activation has been prevented.
Ensure that the Millivolts LF Calibration has been completed. In the event of damage, the shipping container and cushioning material should be kept for the carrier’s inspection. Age — Very old instruments can suffer from age related failures caused by normal deterioration of components and assemblies over time.
Refer to Section 4, Operating Routines. Select lest to carry’ out the test routine described hi Section 4.
