Dial Indicators
-
1. Always select the dial test indicator that best fits the application.2. Care should be taken while using a dial test indicator, try not to jolt the indicator, should you be unfortunate and drop a dial test indicator, get it re-calibrated/repaired before reusing it.3. Replace worn contact points only with those of a similar length from the centre of the ball stylus to the abutment shoulder.4. Always clean dial test indicators after use with a lint free paper or cloth and store the indicator in its box or in a dust free area.5. When using a dial test indicator, always position the dial test indicator in a horizontal plane to the surface media.6. Always use a rigid stand for mounting the dial test indicator.7. When measuring a rotating object, either between centres or in a vee block, ensure that the object is rotating in the correct direction. Never rotate the workpiece towards the contact point.8. When measuring a sliding object, only take readings when the object is moving directly towards the contact point, never away from the contact point or in a sideways manner.9. Avoid parallax errors by reading the dial directly from the front and square on to the dial.10. Never oil a dial test indicator as this attracts contamination, should the movement become erratic then the dial test indicator should be submitted to a reputable repair agent.11. Try not to expose dial test indicators to direct sunlight or in a high humidity environment.12. Never use a dial test indicator that has not been calibrated, if in doubt consult an appropriate authority.

Dual Channel HV Amplifier with Phase Inverter
A400DI
-
This unit contains two independent A400 amplifiers that share common ground reference and power supply. Please see A400 page for technical details.It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground.
