Display (Lcd) - Gossen MetraWatt METRAHIT ENERGY TRMS System Multimeter Operating Instructions Manual

Setting the Reference Value
Ð Plug the measurement cables into the instrument and measure
a reference value (max. 25,000 digits, or 5000 digits in 10 A
range)
Ð Briefly press the ZERO | ESC key.
The instrument acknowledges storage of the reference value
with an acoustic signal, and the "ZERO REL" or the "REL"
symbol appears at the LCD. The value measured at the mo-
ment the key is pressed serves as a reference value.
Ð The reference value can be cleared by once again pressing the
ZERO | ESC key.
Notes Regarding Relative Measurement
• Relative measurement effects the main display only.
• In the case of relative measurement, , F or AC quantities may
also appear as negative values.

plus pole of the measured quantity is applied to the "" input.
Overranging
"0L" (overload) is displayed as of 61,000 digits.
Exceptions: "OL" appears at the display as of 6100 digits for mea-
suring functions with a measuring range span of 6000 digits.
