Other Features (continued)
Manual Ranging (R-H)
The range hold button (R-H) activates manual ranging.
Press the R-H button to cycle through available ranges.
Pressing and holding the R-H button for approximately two
seconds returns the meter to autorange mode and “auto” will
be displayed in the upper left corner of the display.
Data Hold (D-H)
Press the D-H button at any time to freeze the reading on the
LCD display. This function is useful when measuring in
locations where the display is difficult to read.
LED Indicators
The 275 is equipped with three LED indicators at the top near
the jaw.
HI-V This indicator flashes and the 275 beeps
when the test leads are in contact with a
voltage of 30V AC/DC or more.
NCV This indicator illuminates when the non-
contact voltage detector senses a voltage.
This is the visual indicator of continuity. This
LED also flashes anytime the buzzer beeps.
Other Features (continued)
Peak Hold Mode (P-H)
The Peak hold function allows the 275 to display the the
maximum and minimum peak voltage or current. This is
helpful when measuring inrush current.
NOTE: Peak mode can display up to 70 counts on the dis-
play when first activated. For example, if the 275 is set to
the ACA function and manually ranged to the 40A range,
when P-H is activated the display can read up to 0.70.
This is normal for this function.
1. Manually select the range for the function and set
the meter up to perform a measurement as outlined
earlier in this manual.
2. Depress and hold the P-H button until CAL is dis-
played. Once CAL clears from the display you may
make a measurement. Press P-H repeatedly to cycle
through the maximum and minimum peak readings.
Press and hold the P-H button for two seconds to
return to normal operation.
For inrush current, after CAL clears press the P-H
button and then supply power to the device under
test. The 275 will capture the maximum and mini-
mum peak inrush.
