9. PREPARATIONFOR USE
The TG110DL comes with two AA-size alkaline batteries installed in its battery chamber. To check for satisfactory
battery life, press the ON/OFF touch command to turn power on. A Battery Icon appears on the left side of the LCD
display indicating the current battery charge level. Approximately 150 hours of typical use remains from a fresh set
of batteries. If the display readout fails to register more than 20% scale then the batteries need replacement.
When charge level becomes marginal, the Power-Guard Marginal Cutoff feature automatically turns the power off
until the batteries are replaced.
Battery Replacement:
Loosen (counterclockwise) the battery cover on the bottom of the gauge with a small coin
or screwdriver. Remove the discharged batteries and replace them with two new AA-size alkaline or NiMH
rechargeable batteries. Install them with proper polarity, negative side to be in contact with the battery cover.
Replace the battery cover into the gauge and tighten by turning clockwise. Re-establish the gauge calibration
settings whenever the batteries are completely discharged, removed, or replaced.
Probe Selection:
A variety of probes are available to optimize performance for the broad spectrum of gaging
applications that may be encountered. The TG-506 Transducer should be used for most applications and surface
temperatures up to about 225ºF.
There are also the TG-556, TG-790, and TG-208 transducers designed for intermittent contact of surface
temperatures up to 600ºF (316 C).
An Ultrahigh-temperature probe having a fused quartz delay line, like the TQ-506, should be used on surface
temperatures between 600 to 1000ºF (316-538 C).
Smaller sized Mini-Probes like the TG-502 and TG-702 transducers are available for use on smaller surface radii or
for gaging in confined locations.
Refer to the probe list in the Accessories section to select the best probe suited for your application. For best
results, use probes manufactured by NDT Systems, Inc whenever possible.
Probe Attachment:
All transducers except the
“Mini
-
Probes” have a detachable dual cable for connecting to the
TG110DL. Connect the dual cable (LMD1) to the probe using the cable end with the smaller red-sleeved and black-
sleeved Microdot screw-on connectors (certain transducers may require attaching the red-sleeved and black-
sleeved connectors to the correspondingly marked polarized connectors). Connect the other end of the dual cable
with the larger push-on/pull-off LEMO connector to the corresponding connectors located on top of the gauge. Be
certain to connect the red-dot marked connector to the gauge connector with the adjacent red dot.
