Warranty:

Monroe Electronics, Inc., warrants that each

instrument and sub-assembly manufactured by them
shall be free from defects in material and workmanship
for a period of one year after shipment from the factory.
This warranty is applicable to the original purchaser

Calibration:

Monroe Electronics instruments are factory-

calibrated prior to shipment. Recalibration should be
performed annually, or more frequently if specified by
contract or company policy. Your instrument should
also be recalibrated any time it has been repaired or
tampered with. We are happy to recalibrate your
instrument for you at a reasonable cost, or provide
information and procedures on calibration upon request.

Specifications are based on use of Models

1017AEL or 1017ASL probe at 0.005" probe to surface
spacing. To achieve best drift characteristics, probe
must be purged with filtered air or inert gas in a stable
laboratory environment.

For further details, see individual data sheets for

Models 244 and 1017A or consult the factory.

Probe-to-surface spacing:

Probe-to-surface spacing should not exceed 0.100” in
normal use, optimum being between 0.005” and 0.015”.
Noise, drift, and speed or response deteriorate directly
with increased probe-to-surface spacing. Measurement
accuracy, however, can be made independent of probe-
to-surface spacing with proper use of the front panel
balance and zero controls.
