TB 9-1430-201-50

b. Adjustments. No adjustments can be made.

13. Final Procedure

a. Deenergize and disconnect all equipment.

b. In accordance with TM 38-750, annotate and affix DA Label 80 (US Army

Calibration System). When the TI cannot be adjusted within tolerance, annotate and affix

DA Form 2417 (Unserviceable or Limited Use tag).

SECTION V

CALIBRATION PROCESS FOR

ESI, MODELS DV411 AND DV412

NOTE

Unless otherwise specified, verify the results of each test, and

take corrective action whenever the test requirement is not

met, before continuing with the calibration.

14. Preliminary Instructions

a. Personnel should become familiar with sections I, II, and V before beginning

calibration.

b. Items of equipment used in this procedure are referenced within the text by common

name and item identification number as listed in tables 2 and 3. For the identification of

equipment referenced by item numbers prefixed with A, see table 2, and for prefix B, see

15. Input Resistance

a. Performance Check

(1) Connect resistance bridge (A2) UNKNOWN terminals between TI IN and COM

terminals, using Kelvin clips (B4).

(2) Measure TI input resistance. Resistance bridge will indicate between 9,995 and

10,005 ohms or 99,950 and 100,050 ohms, depending on input resistance (10 k ohms or 100

k ohms) of TI.

b. Adjustments. No adjustments can be made.
