2. Safety

Safety Notes

 Before operating the device, you must read, understand, and follow all instructions,

dangers, warnings, cautions, and notes.

 FLIR Systems reserves the right to discontinue models, parts or accessories, and other

items, or to change specifications at any time without prior notice.

 Remove the batteries if the device is to be stored for an extended period.

Warning Statements

 Do not operate the device if you do not have the correct knowledge. Incorrect operation

of the device can cause damage, shock, injury or death to persons.

 Do not start a measuring procedure before you have set the function switch to the

correct position. Failure to do so can cause damage to the instrument and can cause
injury to persons.

 Do not change to the resistance mode when measuring voltage. This can cause damage

to the instrument and can cause injury to persons.

 Do not measure the current on a circuit when the voltage increases to more than 1000 V.

This can cause damage to the instrument and can cause injury to persons.

 You must disconnect the test leads from the circuit under test before you change the

range. Failure to observe this warning can damage the instrument and cause bodily
injury.

 Do not replace the batteries before you remove the test leads. This can cause damage to

the instrument and can cause injury to persons.

 Do not use the device if the test leads and/or the device show signs of damage. Injury to

persons can occur.

 Be careful performing measurements if the voltages are > 25 VAC rms or 35 VDC. There is

a risk of shock from these voltages. Injury to persons can occur.

 Do not do diode, resistance or continuity tests before you have removed the power from

capacitors and other devices under test. Injury to persons can occur.

 Be careful when performing voltage checks on electrical outlets. These checks are

difficult because of the uncertainty of the connection to the recessed electrical contacts.
You must not rely solely on this this device when determining if the terminals are not
“live”. There is a risk of electrical shock. Injury to person can occur.

 Do not touch expired/damaged batteries without gloves. Injury to persons can occur.
 Do not cause a short circuit of the batteries. This can cause damage to the instrument

and can cause injury to persons.

 Do not put the batteries into a fire. Injury to persons can occur.
 Use extreme caution when the laser pointer is on.
 Do not point the beam toward anyone's eye or allow the beam to strike the eye from a

reflective surface.

 Do not use the laser near explosive gases or in other potentially explosive areas.
 Refer to the CAUTION statement label (shown below) for critical safety information.

5. Meter Power

5.1 Powering the Meter

1. Set the function switch to any position to switch on the meter.

2. If the battery indicator shows that the battery voltage is low, if one of the Low
Battery screens appears (Fig. 5-1), or if the meter does not power on, replace the three
(3) ‘AA’ batteries. See Section 12.2, Battery Replacement. If using the Model TA04
charging system, please recharge the rechargeable battery.

FIG. 5-1 Low Battery Alerts

5.2 Auto Power OFF (APO)

The meter enters sleep mode after a programmable period of inactivity, to customize
this setting please see Section 7.1.2, APO (Auto Power OFF). The default time-out is 10
minutes. The time can be set to 1, 2, 5, or 10 minutes (select OFF to disable the APO).
20 seconds prior to entering APO mode, the meter beeps; at this point, press any
button or turn the Rotary Switch to reset the APO timer.

5.3 Battery Type Selection

The user must enter the battery type (Lithium or Alkaline) in the General Settings
menu before use. This allows the meter to display battery status as accurately as
possible. Refer to Section 7.1.5, Battery Selection.
