Probe Test
Turn the selection knob on the meter to the “PROBE TEST” position.
With the “ZERO ADJ.” knob in a center position, the meter should read
between the green lines (in the “OK PROBE TEST” area). If it does
not, the probe has been damaged and should not be used. A defective
probe cannot be replaced in the field and should be returned to
ETS-Lindgren for repair. See the Product Information Bulletin included
with your shipment for details regarding returning instruments for
repair.
