Q1 | Regarding to Scanner Card (GDM-SC1), could GDM-8255A memorizes the channels setting in the user-default? |
No. Due to the scanner card setting is saved at the volatized memory of GDM-8255A, thus it is unable to be saved into the user-default.
Q2 | Why the GDM-825xA series can not remember the last condition whilst turn the power on? |
The GDM-825xA series is always running the factory-default condition when every time turns the power back on. To keep last condition for the next time power on, you should save the current condition as a user-default and then set the user-default to replace the factory-default when turn the GDM-825xA series back on at every time. For the method to save & recall a user-default, please refer to Save / Recall chapter in user manual.
Q3 | What is the dual display measurement for the GDM-825xA series? |
The GDM-825xA series provide two display meters; it allows using the 1st display to show one measuring item and using the 2nd display to show another item, thus viewing two different measurement results at once. The following table shows the available options:
●:Available, ─:Not available
1st Display | 2nd Display | ||||
ACV | DCV | ACI | DCI | Hz/P | |

Note | In the dual display mode, the resistance needs to be larger than 1MΩ. |
Q4 | Does any require for RS232 cable whilst connecting with GDM-825xA series? |
Yes, you need to use the Null Modem cable which the transmit (TxD) and receive (RxD) lines are cross-linked.
Q5 | What is the message terminator for GDM-825xA series? |
The GDM-825xA series accept only LF (line feed) as the message terminator whilst giving a command.
Q6 | What is the RS232 configuration for GDM-825xA series? |
The GDM-825xA series RS232 configuration as below:
RS-232 configuration | Connector | DB-9, Male |
Baud rate | 115200 (default) | |
Data bit | 8 | |
Parity | None | |
Stop bit | 1 | |
Flow control | None |
Q7 | Regarding to GDM-825xA series, what is the Calibration Key (GDM-01) used for? |
The Calibration key (GDM-01) is used for firmware upgrade.
Q8 | The GDM-825xA series performance does not match the specifications. |
Make sure the device is powered On for at least 30 minutes, within +18°C~+28°C. This is necessary to stabilize the unit to match the specifications.
Q9 | Regarding to GDM-825xA series, I pressed the EXIT key but cannot get out of Scanner mode. |
Press the EXIT key, followed by the ACV (Scan) or DCV (Step) key.
Q10 | Regarding to GDM-825xA series, what is the Output key used for? |
The Output key is used for turning the display output on or off.
Q11 | What is different between GDM-8255A and GDM-8251A? |
Q12 | What is the message terminator for LCR-800 series? |
The LCR-800 series accept the following as the message terminator whilst giving a command.
Message terminators | <NL^END> Or <NL^J> |
New line or ASCII line feed character (HEX 0A) |
<CR^M> | Carry return character (Hex 0D) |
