5.1 BATTERY INSTALLATION
HI 9819X
are supplied with 4 alkaline, size AA batteries.
The battery symbol on the LCD indicates the remaining battery life. The meter
has a low battery warning, and when the symbol starts blinking, batteries should
be replaced with new ones. When the batteries are discharged the meter will
automatically shut off to avoid erroneous readings.
Replace batteries in nonhazardous areas only.
Remove the 4 screws on the rear of the instrument and insert the batteries
observing polarity.
Note: Do not mix old and new alkaline batteries.
For a correct installation:
• Grease the sensor O-ring with the lubricant found in the probe maintenance
kit. DO NOT SUBSTITUTE other grease/lubricants as it may cause the O-ring
to swell.
• Insert the sensor into the correctly color coded opening while positioning the
connector key toward the center of the probe. Make sure the connector is
seated correctly (the sensor will no longer move freely) before tightening the
locking threads with your fingers.
• Continue to tighten the locking threads with the tool supplied in the maintenance
kit until the sensor is secured tightly against the probe body.
• To protect the sensors, screw the protective shield onto the probe body.
• With the meter off, connect the probe to the DIN socket on the bottom of the
meter. Align the pins and key then push the plug into the socket. Secure the
probe by attaching the carabinier of the probe to the meter piston.
• Turn on the meter by pressing the ON/OFF key. The meter should automatically
recognize the installed sensors and identify them on the probe status screen. If
you have an error message or the sensor is not recognized, reconnect the
sensor(s) or probe and try again.
