OPERATION
4.1 Functions
4.1.1 Data Hold
• The last reading may be held on the display by pressing
the Hold button. The symbol will be displayed.
• Whenthehelddataisnolongerneeded,releasethe
hold function by pressing the Hold button again.
4.1.2 Manual Range Mode (Model 503 only)
• The Model 503 operates in an Auto-ranging mode
(AUTO displayed) by default. Manual-ranging in V
(400V,600V),andA(40A,400A)isavailable.
Press and hold the RANGE button. When the range
changes(decimalpointshift),releasethebutton.
• The symbol is displayed in the manual range mode.
• Press and hold the RANGE button for more than 2 sec-
onds to re-enter the Auto-ranging mode.
4.1.3 (Relative) Zero Mode (Model 503 only)
• Press the ZERO button to enter the Zero mode - the
symbol turns on and the display is set to zero.
• Toviewtheoffsetvalue,presstheZERO button again.
The
annunciator blinks and the memorized offset
value will be displayed. This value will be subtracted from
thenextmeasurement.
• Whenthezeromodeisactivated,themeterautomati-
cally enters the manual range mode (the auto-range
function will be disabled).
• Press and hold down the ZERO button for 2 seconds
toexit.
