Adjustment Procedures

WARNING Do not perform any of the following adjustments unless you are a qualified, service-trained technician, and have read the WARNINGS and CAUTIONS in this manual. Adjustment procedures should be performed in the order shown in this manual.

Adjustment

Conditions

General Procedure

See Table D-1, Recommended Test Equipment, for test equipment requirements. For optimum performance, all adjustment procedures should comply with following test conditions:

Ambient temperature of the test area is between 18°C and 28°C and stable to within ±1oC.

Ambient relative humidity of the test area is <80%.

Must have a one hour warm-up with all input signals removed.

Shielded twisted Teflonâ insulated cable or other high impedance, low dielectric absorption cable is recommended for all measurements.

Keep cables as short as possible. Long test leads can act as an antenna causing pick-up of ac signals and contributing to measurement errors.

Follow each adjustment by a performance verification test for added confidence. We recommend the following general procedure.

1.Perform the Zero Adjustment Procedure

2.Perform the Gain Adjustment Procedure(s)

3.Perform the Performance Verification Tests.

CAUTION

ORDER OF ADJUSTMENTS REQUIREMENT. Range adjustments

 

MUST be performed in the order given in the adjustment table. An

 

accurate range adjustment requires the range adjustments prior to

 

the one in progress be within specification.

 

 

 

 

CAUTION

ZERO ADJUSTMENT REQUIREMENT. The zero adjustment must

 

be a recent adjustment prior to performing the gain adjustments. It

 

is recommended you perform the zero adjustment one time just

 

before performing the gain adjustments.
