11.18 Set Time (“SET TI”)
This item is a special 3-byte value in Hex format. It sets the time on the display when the front-panel RESET
button or the corresponding external reset is activated. It uses prefixes R and W and the suffix is 1E.
The data format is identical to that of the Setpoint 5 value in Section 11.17.
EXAMPLE: You want to set the time to 12:30:20 of meter 15. Send the command *15W1E0C1E14. The
meter will respond with 15W1E.
11.19 Output Scale
This item is 3 bytes (6 characters). It uses the prefixes G, P, R, and W with the suffix 26.
Bits 0 through 18 assign the Hex value.
Bit 19 assigns the sign where 0 corresponds to a positive value and 1 corresponds to a negative value.
Bits 20 through 23 assign the decimal number as follows:

Maximum/Minimum values are ±500000.
EXAMPLE: You want to read the output scale value from RAM of meter 15. Send the command *15G26.
The meter responds with
15G2689EDDA.
Since the meter is in ECHO mode, G26 is the echoing responds, and the value to be interpreted is 89EDDA.
The last character is 8. This is the decimal number, and according to the table above it corresponds to 10 -7 .
The next character, 9 has a most significant bit of 1, therefore the value is negative.
The rest is 1EDDA, which is 126426, therefore, the value is –126426 x 10 -7 = -0.0126426.
Important Note: The true value for the output scale factor is stored in EEPROM. When the meter is operating,
it combines this value with the calibration scale and the offset of the Isolated Analog Output Board and stores
the “modified output scale value” in RAM. Therefore, a P26 command that writes to RAM should not be used at
all, or should be used very carefully. With G26 the value of the modified output scale can be read.
