Peak Hold Mode (P-H)
The Peak hold function allows the 270 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 270 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.

2.
Manually select the range for the function and set
the meter up to perform a measurement as outlined
earlier in this manual.
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 270 will capture the maximum and mini-
mum peak inrush.
