‘RESET’ ‘RESET’ “RESET2”
then The
Measured
Value
Press the ‘RESET’ the button two times. display will momentarily
show “RESET2” and then will display the currently measured
values.
NOTE: If after zeroing the display with RDF OF, the reading again drifts from zero, the required offset value is the
sum of the current RDG OF value and the current converted offset value. The examples below illustrate the
calculation of required offset values when using an independent decimal. If you are using an active decimal point,
the current converted offset value is simply the negative value of the display reading.
Example 1: You use a RDG OF value of –1.0000 to zero the meter. The next morning, the meter displays 00.0008
at zero input; you need to rezero. The current count value is 000008; shifting this value to the left of the decimal
makes it 08.0000, and making the value negative makes it –8.0000. The required RDG OF value is the sum of the
current RDG OF value (–1.0000) and the current converted offset value (–8.0000):
–1.0000 + –8.0000 = –9.0000
Example: You use a RDG OF value of –1.0000 to zero the meter. The next morning, the meter displays –0.0008 at
zero input; you need to rezero. The current count value is –00008; shifting this value to the left of the decimal
makes it –8.0000, and making the value positive makes it 08.0000. The required RDG OF value is sum of the
current RDG OF value (–1.0000) and the current converted offset value (08.0000):
–1.0000 + 08.0000 = 07.0000
If you require further configuration(s) for your specific application, refer to Sections 9 through 21.
NOTE: Should you receive an error code of any kind while configuring your meter, refer to Section 17 -
Troubleshooting -Display Messages and Troubleshooting Guide.
8.4 Scaling Your Meter Without Connecting A Sensor Using Calculated Values
Your meter can be scaled without connecting a sensor and taking measured values using Input Scale and Offset
(“IN.SC.OF”).
The typical configuration and scaling of your meter is a 0-100 mVdc input with a display equal to 0 to 100000. If
your meter has not been rescaled and your input is 4-20 mAdc, you can use the factory scaling “0” as your
“INPUT1” and “100000” as your “INPUT2” and proceed with the step-by-step procedure in Section 8.4.1.
If you need to change your input signal, you must rescale your meter as described in the following steps:
8.4.1 Preparing Your Meter For Scaling With Input Scale And Offset
If you are changing your input signal you must follow the instructions for installing the correct jumper positions as
described in Section 6 and the sensor connections as described in Section 7.
WARNING: Do not connect your AC meter power until all input jumpers and sensor input connections are
completed. Failure to do so could result in damage to your sensor and/or the meter.
The following procedure will direct you step by step in preparing your meter for rescaling using Input Scale and
Offset (“IN.SC.OF”).
NOTE: The following procedure will scale your meter to display in microvolts and insure that your final scaling is as
accurate as possible.
