Test Conditions: This certificate supersedes Certificate of Conformance number 89-086A4 and is issued to
indicate the transfer of ownership from Tyrel Corp. to Digi-Star LLC. The NTEP Certificate of
Conformance 89-086A4, though inactive, remains in effect to cover those devices previously sold and
installed under the original name. Previous test information and documentation provided by the company
was reviewed. The test conditions for the original type evaluations are listed below for reference.
Certificate of Conformance No. 89-086A4: This Certificate supersedes Certificate of Conformance No.
89-086A3 and is issued to include the Model TCX-1000 and include the 12 VDC battery option. The
Model TCX-1000-B was tested at –10 °C to verify operation of the LCD display at low temperatures.
Additionally, low battery tests were conducted using a variable DC voltage power supply.
Certificate of Conformance No. 89-086A3: This Certificate supersedes Certificate of Conformance No.
89-086A2 and is issued to remove the B option for use of a 12 VDC power input instead of 117 VAC
power. No testing was done with this power source and the B option was included in error. Test conditions
for Certificate of Conformance No. 89-086A2 have been revised to remove the reference to the B option.
Certificate of Conformance No. 89-086A2: This Certificate supersedes Certificate of Conformance No.
89-086A1 and is issued to include the -L suffix. The addition of the suffix has no metrological effect on the
device, and no formal testing was required.
Certificate of Conformance No. 89-086A1: This Certificate supersedes Certificate of Conformance 89-
086 and was issued to add optional Model TC-10A. Model TC-10A is the same as Model TC-10 except
that it has extra keys on the front panel to prevent operator errors and a two digit display to show the cut-off
set point. Two internal changes were made to automatically set the dead load and gain switch during
