Number Table 5. Display Features (cont.) Feature Indication -- 0L Overload condition is detected. Error Messages bAtt di'c Replace the battery immediately. In the capacitance function, too much electrical charge is on the capacitor under test. CAL Err Invalid calibration data. Calibrate Product. EEPr Err Invalid EEPROM data. Have the Product serviced. 0PEn Open thermocouple detected. F2_ LEAd Invalid model. Have the Product serviced. W Test lead alert. Shows when the test leads are in the A or mA/μA terminal and the selected rotary switch position does not correspond to the terminal being used. True-rms Digital Multimeter Features Automatic Power-Off The Product automatically turns off if you do not turn the rotary switch or push a button for 30 minutes. If MIN MAX Recording mode is on, the Product will not turn off. Refer to Table 6 to disable automatic power-off. Input Alert™ Feature If a test lead is connected to the mA/μA or A terminal, but the rotary switch is not set to the correct current position, the beeper warns you by making a chirping sound and the display flashes "LEAd". This warning is intended to stop you from attempting to measure voltage, continuity, resistance, capacitance, or diode values with the leads are plugged into a current terminal. W Caution To prevent damage, do not put the probes across (in parallel with) a circuit with power with a lead connected to a current terminal. This can cause damage to a circuit with power and blow the Product fuse. This can occur because the resistance through the current terminals of the Product is very low, and causes a short circuit. 15

Indication
--
0L
Overload condition is detected.
Error Messages
bAtt
Replace the battery immediately.
di'c
In the capacitance function, too much electrical
charge is on the capacitor under test.
CAL
Err
Invalid calibration data. Calibrate Product.
EEPr
Err
Invalid EEPROM data. Have the Product serviced.
0PEn
Open thermocouple detected.
F2_
Invalid model. Have the Product serviced.
LEAd
W
Test lead alert. Shows when the test leads are in
the
A
or
mA/
μ
A
terminal and the selected rotary
switch position does not correspond to the terminal
being used.
Automatic Power-Off
The Product automatically turns off if you do not turn the
rotary switch or push a button for 30 minutes. If MIN MAX
Recording mode is on, the Product will not turn off. Refer
to Table 6 to disable automatic power-off.
Input Alert™ Feature
If a test lead is connected to the mA/
μ
A or A terminal, but
the rotary switch is not set to the correct current position,
the beeper warns you by making a chirping sound and
the display flashes “
LEAd
”. This warning is intended to
stop you from attempting to measure voltage, continuity,
resistance, capacitance, or diode values with the leads
are plugged into a current terminal.
W
Caution
To prevent damage, do not put the probes
across (in parallel with) a circuit with power
with a lead connected to a current terminal.
This can cause damage to a circuit with
power and blow the Product fuse. This can
occur because the resistance through the
current terminals of the Product is very low,
and causes a short circuit.
