Owner manual

Using a ½" hex socket on a

" drive ratchet, connect to the

internal male hex shaft and crank counter clockwise to raise the

platen and apply load to the reference gage and the machine’s

load cell.

Starting from the chart origin, observe the recorder's pen position

and check it against the reference gage reading for each 1000 lbf

of load applied.

If an adjustment other than a zero shift is needed, remove the

recorder from the chassis leaving the cables connected and from

the picture below ﬁnd potentiometer R231 (for the Y axis). With

a small, plastic screw driver turn the pot to increase or decrease

the gain as required.

Calibration of the Flow or X axis is accomplished by measuring the platen

travel with a rule while keeping time with a stop watch (usually

" in 15

seconds is the measured distance and time check) while observing the chart

reading. If the travel is not within .50" +/- .04" on the chart adjust the gain

using pot R131.

Maintenance

The machine and transducers should be kept clean and the machine should not be

over lubricated. Light oiling with synthetic instrument oil at most is required on

exposed spindles and threads; the jack and gear box are serviced with a premium

wheel bearing grease such as Pennzoil 707L Lubriplate Grease applied thru the

grease ﬁtting no more than annually, or when an indication of power train friction

appears.
