Service

WARNING:

The presence of lethal voltages within the instrument means that the user is strictly

forbidden from removing the covers. There are no user-serviceable parts inside the

instruments.

NOTICE:

Should any difficulties be encountered in the use of the THCD-401, it is recommended that

you contact Teledyne Hastings Instruments for advice and instructions. Entry into the instrument or

tampering with the printed circuit board will void the warranty.

Calibration

There is no user calibration for the THCD-401. It is recommended that the instrument be returned periodically

to Teledyne Hastings Instruments for a ‘factory calibration’. This will ensure optimum performance throughout

the life of the product.

Adjustment

WARNING:

The presence of lethal voltages within the instrument means that the user is strictly

forbidden from removing the covers. There are no user adjustments in the instrument.

Cleaning

A dirty instrument may be wiped clean with a damp cloth, then wiped dry immediately.

WARNING:

Under no circumstances should the instrument be wetted directly or left damp.
