Product Overview
The EasyLyte analyzer is a direct measurement ion-selective electrode (ISE) system which uses
Sodium (Na), Chloride (Cl), Potassium (K), and Lithium (Li) sensitive components to measure
electrolytes in either whole blood, serum, plasma or urine.
The analyzer software allows the operator to perform sample analysis, analyzer diagnostics and
maintenance by simply pressing the "YES" or "NO" buttons in response to prompts displayed on
the LCD screen. The EasyLyte analyzer performs the analysis both quickly and cost effectively.
Analysis takes only one minute and utilizes approximately one hundred microliters of whole
blood, serum or plasma; or four hundred microliters of diluted urine.
The analyzer can re-calibrate automatically every four hours and can perform emergency (STAT)
analysis on demand. Results are always displayed on the LCD screen and can also be docu-
mented on paper by an integrated printer.
The analyzer contains a patented reagent system including a modular reagent pack. This pack
provides a minimum of two months supply of solution and also serves as a waste receptacle for
solution and samples after analysis.
System Overview
The EasyLyte analyzer is engineered to make local service feasible. Modular construction is
used throughout the design. The basic operating system consists of a motor which drives a peri-
staltic pump. The peristaltic pump pulls the desired fluid through the system, disposing waste into
a designated compartment inside the solutions pack. A second motor drives a lead screw which
in turn drives a mechanical link-arm assembly. This link-arm assembly moves the sample probe
vertically allowing the probe inside the solutions valve to aspirate the appropriate fluid for pump-
ing: sample; standards; or air. The sample detector in the fluid line positions the fluids.
Please note that mechanical and electrical assemblies can be replaced. Follow the instructions in
the TROUBLE SHOOTING SECTION to determine if assembly replacement is necessary. Refer
to the Replacement List in this section which lists replaceable assemblies, components, and
appropriate catalog numbers.
If repair to any electrical assembly is necessary, consult Schematics in the APPENDIX
SECTION for further detail. Service personnel are encouraged to contact Medica directly with
any problems or concerns relating to electrical assemblies.

Troubleshooting 15
Troubleshooting Overview
This section describes troubleshooting the mechanical and electrical functions of the EasyLyte
analyzer. This section is based on the principle of replacing suspected faulty assemblies with
new assemblies. Medica recommends keeping an inventory of functioning test assemblies
for troubleshooting the EasyLyte. Refer to the Troubleshooting Guide in this section to deter-
mine the cause and corrective action that must be taken to properly service the EasyLyte
Analyzer.
Since EasyLyte Analyzers with serial numbers below 6100 are assembled using Power
Supply, part no. 05001065 and CPU, part no. 05001063 the troubleshooting instructions
differ in certain areas. Please refer to the serial number, located on the back panel of the
analyzer, to identify which instructions to follow.
For information on troubleshooting the EasyLyte Analyzer flow system and consumable items,
consult the EasyLyte Operator’s Manual. See the Replacement List in the PRODUCT
DESCRIPTION SECTION of this manual for a complete listing of all consumable items and cata-
log numbers. For information on troubleshooting the EasyLyte EasySampler consult
