Two examples are given below. If the distortion specification is to be verified, the measurement equipment must be selected with care.

This applies particularly to the I Amp shunt. Codes LO to L3 configure the output string notation: Use the general sequence: Sensitive measurements are being made. Resistance — a set of standard resistors covering ion to looMn, The ion to lOkn should be 4-wire type. Resistance Use tlie General Sequence: Reference to the appropriate calculation is given in each procedure.

Accidental or unauthorized use of the calibration routine is prevented by a key-operated switch on the instrument rear panel. Over-voltage protection is provided, and the Output lines are fused.

Ensure that the DVM is still connected to the terminals as shown in Fig.

Routine adjustment of tite resistor is not dztron. The controller would perform other tasks during this period. Always keep interconnecting leads as short -as possible, especially unscreened lengths.

Measure Resistance value and record on Table 3.


The labelled facility is not selected. The rear output option is not recommended for catron performance in calibrating high bandwidth, low level instruments. The polarity LEDs change over only when the opposite polarity appears at the output terminals.

Full Range checks Press Spec Key. Load impedance too high — Excessive internal temperature. Programs for 2-wire resistance in F4. Low Voltage State Approx.

Select AC At operations: Ensure familiarity with normal operation of the described in this Handbook. Band set by On DC voltage and current, a polarity sign is present except at zero. A Key LED lit signifies that conditions are valid for the selected operation, and not merely that the key has made contact. Resolution as listed in table. These terms and conditions are subject to change at any time and without notice. During remote operation, the facilities of Error mode are excluded, as they can easily be programmed into the controller.

Do not connect null detector to shunt yet Preferred shunt values are as follows: To allow the same value to be set on the DC Voltage source for each range, the shunts may be of five decade values.

By sending a V code the conlrolier interrogates the to obtain, information about its present status. At any time, the instrument status is described by the combination of LET states, display values and display messages. An AC DVM is standardized to the appropriate voltage, and the Current range is calibrated when the voltage across its shunt is correct.


Figures of performance are quoted in the specifications of Section 6, related to time since calibration. These instruments can produce or measure lethal voltages at their terminals. The positive and negative zeroes are now both aligned to the Calibration Source zero.

The connections to the resistor remain the same, but the display value includes the resistance of the connections form the Ei and Lo terminals to the resistor. The correct calculations are identified In the individual procedures.

Remote Sense is automatically deselected. Four points are important: Alternative Millivolt Verification Procedure 3. Testing Steps If the instrument is smoking or has a bad smell coming from it turn it off immediately and contact us for further instruction. Sending the I command will store the subsequent 1 6 character string in memoi 7.

Store Xi — Gain Cal. Press the correct-polarity ON key and allow 5 minutes to dxtron. Fixed or Adjustable Voltage Standard? Not active – disabled by WO P? During this sequence observe that: Refer to page The right- hand blocks generally deal with function and output definition, whereas the left-hand blocks are concerned with frequency, mode and terminal configurations.

These modify the values which control the output.
