the sign that the system halves are shorted together.
e. If only one half of an acceptable system is being properly tested, you will see the LED’s light
up while a emp ng to automa cally “range”. The LED light sequence will be:
(1) Ini ally, the HIGH FAIL and LOW BATT. LED’s should light briefl y.
(2) The HIGH FAI L LED goes off , the PASS LED comes on and the LOW BATT. LED remains
on.
(3) The PASS LED remains on and the LOW BATT. LED goes off .
(4) An audible “Beep” begins to sound when the test is completed and the Wrist Strap
is within the acceptable resistance range while being worn.
f. Repeat the procedure with the other half of the cuff assembly and look for the same ac-
ceptable results.

be dirty or damaged, or the conductor and resistor may be greater than 1.0x10 7 ohms.
